DISSOLVABLE FILMS AND METHODS INCLUDING THE SAME This application claims priority to U.S. Provisional Application Serial No. 60/582,821, filed June 28, 2004, which is herein incorporated by reference in its entirety. The present invention is directed to dissolvable membranes or films and methods incorporating the same. For example, the present invention is directed to arrangements including a container, a substance and a dissolvable membrane, as well as methods incorporating the same. In the following discussion certain articles and methods will be described for background and introductory purposes. Nothing contained herein is to be construed as an "admission" of prior art. Applicant expressly reserves the right to demonstrate, where appropriate, that the articles and methods referenced herein do not constitute prior art under the applicable statutory provisions. There are many scientific and industrial arrangements and processes that involve the introduction of fairly precise amounts of one or more substances into a container. Depending on various factors such as the nature of the substance introduced, the construction and properties of the container, as well as the technique used to introduce these substances, it is a common occurrence that some of a substance introduced into the container sticks to the walls of the container in a manner that prevents it from being combined and/or interacting with other substances in the container. When the nature of the process calls for precise amounts of the various substances to be combined, the above-described "sticking" problem can have a significant and undesirable impact on the desired outcome of the process. In addition, while automation is desirable in the introduction of substances, it can prove difficult to precisely deliver small quantities of substances. Thus, when precise amounts of substances are called for, it is a common practice to measure and introduce these substances into a container by hand. This labor intensive procedure is clearly less than ideal from an efficiency stand point. One example of the type of scientific or industrial process referred to above is the isolation and/or separation of biological components from a sample. One way of accomplishing this isolation and/or separation involves introducing a biological sample, magnetizable particles, and possibly other substances into a tube, usually gravimetrically or via a pipette. One or more of the biological components present in the tube become associated with the magnetizable particles. Magnets are then caused to come into close proximity to the tube wall(s) causing the magnetizable particles, with the biological component(s) attached thereto, to be drawn to the wall(s) of the tube. The remainder of 5 the constituents, present in the tube can then be removed, thereby separating the biological component(s). Various further process steps can be employed to achieve a desired objective. The walls of the tube and the pipette tip often possess a surface charge that can 10 attract substances thereto. Thus, for example, the introduction of magnetizable particles into the tube poses the above-described problem in that they can often stick to the walls of the tube or pipette in a way that prevents them from properly associating themselves with the rest of the constituents in the tube. Moreover, even if care is taken to prevent the sticking problem when the particles are first introduced, subsequent movement of 15 the tube with the particles contained therein can cause the particles to be thrown against, and stick to, the walls of the tube. Since processes such as the one described above often involve small sample sizes and/or rely upon precise amounts of the various substances to mix together in order to produce a desirable or accurate result, the sticking phenomenon poses a significant problem in the accuracy and reliability in such 20 isolation and/or separation techniques. Therefore, there is a need in the art, in general to provide arrangements and methods that facilitate more accurate introduction and association of substances within a container. There is also a need in the art for arrangements and methods that promote 25 more accurate and efficient introduction and association of substances involved in the isolation and/or separation of biological components from a sample. Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that 30 any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application. Disclosure Of The Invention 2 Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of 5 any other element, integer or step, or group of elements, integers or steps. The present invention satisfies the above-described needs, and others, by providing arrangements and methods that reduce, if not eliminate, sticking of one or more substances to a wall of a container in a way that prevents its proper association 10 with other substances and constituents within the container. The present invention also provides arrangement and techniques that facilitate automation. The present invention additionally provides arrangements and methods that allow for a precise quantity of a substance to be introduced into a container.

FIGS. 2A-2G are schematic illustrations of processes and arrangements according to the principles of a second aspect of the present invention. FIGS. 3A-3F are schematic illustrations of further processes and arrangements 5 practicable by implementation of the principles of the present invention. FIG. 4 is an image of the results of a PCR procedure performed according to one aspect of the present invention. The principles of the present invention will now be further described by the following 10 discussion of certain illustrative embodiments thereof and by reference to the foregoing drawing figures. As used herein, "biological sample" means any substance comprising bodily fluid or matter including, but not limited to, blood, plasma, serum, urine, bone marrow aspirates, cerebral spinal fluid, tissue, cells, food, feces, saliva, hair, oral secretions, nasal secretions, 15 buccal cells, bronchial savage, cervical fluids, lymphatic fluids, sputum, and swabs containing any of the foregoing. The above-referenced bodily fluid or matter may be collected from any source. For example, the source is not limited to humans. As used herein, "magnetically-responsive particle" means a particle is capable of having a magnetic moment imparted thereto or otherwise moveable under the action of a 20 magnetic field. As used herein, "overlies" means an orientation that, during ordinary usage or field of reference, is vertically above the referenced object or substance. As used herein, "readily dissolvable" refers to the capability of a material or film to be broken down when contacted by a selected substance(s) at a rate, and to an extent, such that 25 the material can be readily utilized in a desired scientific or industrial process without causing undue delay. For example, "readily dissolvable" means the Hansen parameters for a chosen solvent lie within the solubility volume or area for the material, as plotted on a Hansen solubility map. See, e.g., "Hansen Solubility Parameter System," DuPont Nylon Intermediates and Specialties, publication W-400473, 12/2000. 4 As used herein, "non-specifically bound" means a binding mechanism that does not occur via a receptor, capture agent, or the like, which would selectively couple with a specific target substance. As used herein, "specifically bound" means a binding mechanism that occurs via a 5 receptor, capture agent, or the like, which would selectively couple with a specific target substance. As used herein, "film" means a member with opposing major surfaces. The term "film" is not intended to be limited to a particular geometry or shape. For example, it is contemplated by the present invention that the film can be substantially planar, or may be 10 provided in the shape of a solid or hollow polygon, sphere, or oblong body. The terms "film" and "membrane" are used interchangeably herein. As previously described, the present invention is directed to a readily dissolvable film and methods incorporating the same. The dissolvable film utilized by the present invention can have any suitable composition so long as it achieves the functional objectives described 15 herein. The readily dissolvable film of the present invention can be formed, at least in part, from known dissolvable substances. For example, any organic or inorganic polymeric material, or a material derived from one or more such materials, characterizable as readily dissolvable could be utilized. Such substances may include cellulose based or derived materials such as low viscosity hydroxyalkylmethyl cellulose or carboxymethyl cellulose. 20 Other suitable materials may include a combination of carboxylic hydroxyalkyl ester monomer with an ethoxylated or propoxylated hydroxyalkyl (meth)acrylate, polyethylene glycol (PEG), and polyvinyl alcohol (PVA). Formulations containing various amounts or combinations of the above-mentioned substances are also contemplated. Such known substances are utilized, for example, to make dissolvable films that are 25 used as carriers for breath-freshening agents. One such film is described in U.S. Patent No. 6,419,903, the entire content of which is incorporated herein by reference. The film described therein is generally composed of a combination of a low viscosity hydroxyalkylmethyl cellulose, starch and a flavoring agent. Films utilized in connection with the present invention may optionally omit components such as flavoring, coloring, anti 30 bacterial and breath-freshening agents. Films suitable for use in conjunction with the present invention can be made by 5 techniques familiar to those of in the art, such as the technique described in U.S. Patent No. 6,419,903. A suitable technique generally involves forming a solution or slurry containing the constituent components of the film, casting and drying the solution or slurry to form a film. Once dried the film may be cut into segments. Alternatively, the film can be 5 continuously cast and accumulated in roll form. An optional technique for incorporating substances or components into the film can involve producing a film by any suitable technique, and incorporating a component or substance into the film via a surface application technique. For example, the film may be in a state wherein it is not completely dried or cured, the component or substance is then introduced onto the surface thereof, and the drying 10 or curing process completed. The resulting film comprises the component on or near the surface of the film. Modifications of this technique are also possible. For example, a fully dried or cured film may form the starting material. The dried or cured film may then be subjected to a process such as heating or wetting, such that the surface is modified to more readily accept the component or substance. The component or substance can then be added 15 to the modified surface and the film dried or cooled to render a film comprising the component or substance incorporated therein at the surface of the film. Alternatively, a substance or additional component may simply be applied to the surface of a fully dried or cured film. One advantage of the present invention is that an amount of a substance to be released from the film and introduced into a surrounding medium and be precisely controlled 20 by controlling the concentration of the substance present in the film, and the size of the piece of film utilized. Films utilized in connection with the present invention may optionally include a fragrance. In certain processes, such as the analysis of biological samples, the inclusion of a fragrance agent can mask the odor often emitted by such samples, thereby improving the 25 working environment. It is comprehended by the present invention that any suitable substance can be used or provided in conjunction with the dissolvable film. According to one embodiment, the film is utilized in conjunction with magnetically-responsive particles. In this embodiment, magnetically-responsive particles may be separate from the film, or introduced into the film 30 in any suitable manner. For instance, as previously described, the particles can be introduced into the solution or slurry that forms the film so that upon casting and drying the film comprises magnetically-responsive particles dispersed within, and trapped by, a dissolvable matrix. Alternatively, the particles may be incorporated into the film via any of the surface 6 application techniques of the type described above. Upon dissolution of the film, the magnetic particles are released, and can be, for example, dispersed into a substance or mixture acting as a solvent. The magnetically-responsive particles can be coated or uncoated, treated or untreated, 5 and/or lack any type of surface modification. The magnetically-responsive particles of the present invention may be designed to specifically or non-specifically bind to a target substance. The magnetically-responsive particles may bind to the target substance via any suitable mechanism, such as electrostatic attraction. Such binding techniques are described, for example, in U.S. Patent Nos. 5,973,138 and 6,433,160, the entire contents of which are 10 incorporated herein by reference. Suitable magnetically-responsive particles may be composed of iron oxide in forms such as ferric hydroxide and ferrosoferric oxide, which have low solubility in an aqueous environment. Other iron particles such as iron sulfide and iron chloride may also be suitable for binding to target substances. In addition, the particles may be composed of silica-coated 15 magnetically-responsive particles. The substance may comprise one or more reagents, such as a lysing agent or protein denaturant, an aprotic solvent, an alkaline agent, or a neutralization buffer. The reagent(s) may be utilized in either liquid or dried-down form. The substance may also comprise one or more reaction components, such as a salt, metal, enzyme, oligonucleotide, primer, additional 20 nucleic acid, or protein. Exemplary salts include EDTA, sodium chloride and potassium chloride. Examples of metals include magnesium, manganese, calcium and other trace metals. In addition, the substance may comprise a stabilization component or media components. . The substance may comprise a material (other than magnetically-responsive particles) 25 that is used to purify, extract, amplify or detect nucleic acids or other biological agents. Such processes and substances are described, for example, in U.S. Patent Application Nos. 10/359,179 and 10/359,180, the entire contents of which are incorporated herein by reference. In this regard, the substance may comprise a material used to reversibly bind to a nucleic acid such as silica particles, silica-coated particles, silica coated membranes, silica gel, hydrated 30 and hydroxylated silica surfaces, glass powder, glass fiber mats, glass membranes, zeolites, ceramics, or polymeric particles coated with a metal oxide or iron salt. 7 It is comprehended by the present invention that a combination of one or more substances may be utilized in conjunction with the readily dissolvable film. For instance, a combination of one or more of the above-described substances may be utilized. When the substance is in particulate form, the shape of the particles is not critical to 5 the present invention. The particles may be of various shapes including, for example, spheres, cubes, oval, capsule-shaped, tablet-shaped, nondescript random shapes, etc., and may be of uniform shape or non-uniform shape. The particles can also have any suitable size. For example, the particles can have an average diameter ranging from sub-micron dimensions to a few microns. 10 Having described various embodiments and characteristics of the film utilized in connection with the present invention, various exemplary methods utilizing the same will now be described. A first embodiment of the present invention is schematically illustrated in FIGS. 1A 1G. As illustrated therein, a container 10 is provided that may comprise a suitable opening 15 20 therein. The container 10 may take any suitable form. According to the illustrated embodiment, the container 10 can generally be in the form of a tube. However, other constructions are contemplated, such as a microwell or array of microwells, a bottle, or a Petridish. A substance 30 is first introduced into the container (FIG. 1A). The substance 30 can have any suitable composition, such as any of the materials identified above for use in 20 conjunction with the readily dissolvable film. According to one embodiment of the present invention, the substance 30 can comprise magnetically-responsive particles having a composition and form according to the previous description. Any suitable technique may be utilized to introduce substance 30. For example, the substance 30 may be introduced by hand or an automated robotic device, 25 A readily dissolvable film 40 is then positioned over the opening 20 of the container 10 (FIG. 1 B). The film 40 can have any suitable composition and/or construction, such as any of the compositions and/or constructions previously described herein. The film 40 can be in the form of a segment that is long enough to span the opening 20, and preferably extend well beyond the boundaries of the opening 20. Alternatively, the film 40 may be in the form 30 of a "continuous" web or roll of such film that is fed over the opening 20 (not shown). The film 40 is then introduced into the container 10 by any suitable mechanism (FIGS. IC and ID). According to one embodiment, the film 40 is introduced into the container 10 by a 8 plunger/punch device 50. The film 40 is positioned within the container 10. The film 40 can be placed at any appropriate location in the container 10. According to the illustrated embodiment, the film 40 is placed such that is overlies the substance 30. Any suitable mechanism or technique may be 5 utilized to position the film 40 within the container 10. According to the illustrated embodiment, the film 40 is pushed down into the container 10 by movement of the plunger/punch device 50 in the longitudinal direction indicated as Di (FIGS. 1C and 1D). Once the film 40 has been properly positioned, the plunger/punch device 50 is withdrawn from the container 10 by withdrawing the plunger/punch device 50 in the opposite 10 longitudinal direction D 2 (FIG. 1 E). Other techniques or mechanisms for placing the film 40 are contemplated. For example, the film 40 may be cut into a piece having a suitable dimension and gravity-fed into the tube, optionally through a chute or funnel. The fihn may also be folded prior to being gravity-fed into the tube. According to another alternative, the film is cut to a specific dimension, then fed into the tube by the use of one or more of a 15 vacuum or positive air pressure. For instance the film is cut above the tube and positive air pressure is used to force the cut film down into the tube. Alternatively, the film is cut at a remote location relative to the tube, a suction device employing a vacuum is used to attach to the film and relocate it proximate to the opening of the tube. The vacuum can then be reversed and the film forced down into the tube with positive air pressure. 20 As shown in the illustrated embodiment, film 40 overlies the substance 30 in a manner such that the substance 30 is substantially trapped in the bottom of the container 10, thereby substantially preventing dislocation of the substance 30 thus preventing an undesirable scattering of the substance 30 along the sidewalls of the container 10 (FIG. 1E). Further optional steps may be performed in the context of the above-described 25 embodiment. For instance, a material or mixture 60 may also be introduced into the container 10 (FIG. 1 F). The material or mixture 60 may optionally include a second substance 70. It is contemplated that material or mixture 60 may include other substances, in addition to the second substance 70. The material or mixture 60 as well as the second substance 70 may have any suitable form or composition. According to one embodiment, the 30 material or mixture 60 comprises a biological sample, and the second substance 70 comprises a constituent component thereof, e.g., cells, microorganisms, nucleic acids, proteins, lipids or carbohydrates. The material or mixture 60 acts as a solvent thereby dissolving the film 40. 9 The material or mixture 60 may optionally include one or more added reagents combined therewith. Upon dissolution of the film 40, the substance 30, which was previously trapped against the bottom of the container 10 is freed and can be disbursed within the material or mixture 60 (FIG. 1G). 5 The description of the previous method, as well as the following description of additional methods, should be read with the understanding that it is contemplated that the methods may consist of, or be limited solely to those steps described herein, that steps in addition to those explicitly described herein may be incorporated into the described methods, that methods comprising subcombinations of the various steps described herein may be 10 practiced, and that methods comprising steps performed in an order different than that described herein may also be practiced. All of these permutations are comprehended by the present invention. A second embodiment of the present invention is schematically illustrated in FIGS. 2A-2G. Generally speaking, this illustrated embodiment of the present invention is 15 substantially similar to the previously described embodiment. Thus, the constituent components and steps previously described in connection with the first embodiment discussed above should be attributed to the second embodiment as well, unless explicitly noted otherwise in the following description. As illustrated, a suitable container 10 is provided, preferably with an opening 20. A dissolvable film 40' is positioned such that it 20 overlies the opening 20 of container 10 (FIG. 2B). The dissolvable film 40' is substantially similar to the previously described dissolvable film, with the following primary distinction. Namely, the dissolvable film 40' is formed such that a substance 30' is incorporated therein. The substance 30' may be the same as substance 30. As previously noted, a film having this construction can be formed by any suitable technique. For example, a slurry solution can be 25 formed comprising a constituent components of the dissolvable film 40' including substance 30'. Upon casting and drying of the slurry or solution, a dissolvable film 40' is provided which is composed of a dissolvable matrix having substance 30' trapped within, and contained by the dissolvable matrix. Alternatively, the substance 30 may be incorporated into a film by any of the previously described surface application techniques. 30 The dissolvable film 40' is then introduced and positioned at any suitable location within the container 10 by any suitable mechanism or technique. As illustrated, the dissolvable film 40' may be introduced and positioned by a longitudinally movable 10 plunger/punch device 50. The plunger/punch device 50 is made to travel in a first longitudinal direction Di (FIGS. 2C and 2D). Once the dissolvable film 40' has been properly positioned within the container 10, the plunger/punch device 50 is withdrawn via movement in the opposite longitudinal direction D 2 (FIG. 2E). The film 40' may also be 5 positioned within the container by any of the alternative techniques described above in connection with the first embodiment. As illustrated in FIG. 2E, the dissolvable film 40' is positioned at the bottom of container 10, thereby insuring that the entirety of the film 40' is contacted by additional substances which may be introduced into the container 10. Additional optional steps may also be performed in conjunction with the above 10 described process. Namely, as described in connection with the first illustrated embodiment, material or mixture 60 may be introduced into the container 10 (FIG. 2F). The material or mixture 60 may optionally include a second substance 70 contained therein. The material or mixture 60 may also optionally include one or more reagents. The material or mixture 60 as well as the second substance 70 may have any suitable composition or form. According to 15 one optional embodiment, the material or mixture 60 comprises biological sample, and the second substance 70 comprises a consistent component thereof, e.g., cells, microorganisms, nucleic acids, proteins, lipids, or carbohydrates. The material or mixture 60 acts as a solvent, thereby breaking apart the dissolvable matrix of the film 40', and releasing the substance 30'. Once released, the substance 30' can be disbursed within the material or mixture 60. 20 The above-described principles of the present invention can be employed in a number of different scientific and industrial contexts. Generally speaking, the principles of the present invention are useful in any arrangement and/or process in which combinations of accurate amounts of various constituent components are needed or desirable. One potential application of the principles of the present invention is the isolation 25 and/or separation of constituent components contained in biological samples. In this context, the container 10 comprises an extraction tube, the substance 30 (or 30') comprises magnetically-responsive particles, the material or mixture 60 comprises a biological sample, possibly combined with additional agents or components thereby forming a mixture, and the second substance 70 comprises a constituent component present in the mixture 60, e.g., cells, 30 microorganisms, or nucleic acids. The methods disclosed above in connection with the description of the embodiments illustrated in FIGS. 1A-lG and FIGS. 2A-2G can be used as the initial stages of such an 11 isolation or separation technique. FIGS. 3A-3F schematically illustrate additional steps which may be performed in conjunction with the previously described steps to carry out an illustrative isolation and/or separation technique. It should be understood that the principles of the present invention can be utilized with numerous types of extraction and/or isolation 5 techniques, and should not be viewed as being limited by the following description of the illustrated embodiment. The mixture 60, comprising the substance 30 (or 30') and a constituent target component of the biological sample 70, formed as described above, and illustrated, for example, in FIG. 1G and FIG. 2G, is manipulated such that the magnetically responsive 10 particles 30 and the constituent component 70 are bound together, thereby forming a complex (FIG. 3A). Any suitable technique may be utilized to bind the magnetic particles 30 with the constituent component. One such technique involves modification of the pH of the mixture 60, thereby altering the surface attraction properties of the magnetic particles 30 and/or the constituent component 70 such that the mutual attraction therebetween is sufficient to bind 15 the two together. One or more magnets 80 are then brought into close proximity with one or more walls of the container, thereby attracting the above-described complex to the wall(s) of the container 10 being subjected to the magnetic field by the magnets 80 (FIG. 3B). The remainder of the mixture 60 can then be removed from the container as illustrated in FIG. 3B. The complex may then be subjected to one or more washing steps. Once the remainder has 20 been removed (FIG. 3C) a second material or mixture 90 can then be introduced into the container 10. The second material or mixture 90 can comprise an elution solution or mixture that causes the magnetic particles 30 and the constituent component 70 to disassociate (FIG. 3D). The magnets 80 can then be brought back into close proximity with one or more walls of the container 10, as illustrated in FIG. 3E. The constituent component 70 can then be 25 removed from the container and subjected to further optional processing steps (FIGS. 3E-3F). Subsequent to the step illustrated in FIG. 3F, constituent component 70 can be subjected to additional processes, such as techniques to detect and/or quantify target analytes. For example, any suitable method of amplification may be used in the methods of the invention. Such methods include, for example, polymerase chain reaction ("PCR"), Strand 30 Displacement Amplification ("SDA"), thermophilic Strand Displacement Amplification ("tSDA"), Self-Sustained Sequence Replication ("3SR"), Nucleic Acid Sequence-Based Amplification ("NASBA"), Qp replicase systems; Ligase Chain Reaction ("LCR"), and transcription-mediated amplification ("TMA"). 12 Subsequent to cultivation or amplification, an assay may be conducted. For example, an analysis can be performed to determine the presence of pathogens such as Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC), Legionella pneumophila, Mycoplasma pneumoniae, Chlamydiaceae Family, Herpes Simplex Virus-1, Herpes Simplex Virus-2, 5 Enterovirus, HIV, HCV, HBV, HPV, West Nile Virus, Influenza A, Influenza B, Respiratory Syncytial Virus, Metapneumovirus, Mycobacterium Avium Complex Direct, Group B Streptococcus, CMV Qualitative, CMV Quantitative, Parainfluenza 1/2/3, Adenovirus, Legionella genus, Legionell micdadei, Bordetella pertussis, Bordetella parapertussis, Tuberculosis, Tuberculosis Culture Confirmation, Mycobacterium Avium Complex Culture 10 Confirmation and M Kansasii Culture Confirmation. Suitable techniques for performing this analysis include the technique embodied in the BDProbeTecTM product manufactured by Becton, Dickinson and Company. Also, genetic testing of nucleic acids present in a sample may be performed. The above-described steps of FIGS. 1A-lG, 2A-2G and 3A-3F as well as the above 15 referenced amplification techniques may be carried out manually, in automated fashion or by a combination of manual and automated steps. The automated steps may be performed with an automated robotic device, which optionally includes automated pipetting, mixing, and magnet positioning functionality. The automated robotic device may be computer controlled. For example, the present invention may be utilized in connection with systems and methods 20 of the type described in U.S. Patent No. 6,672,458, the content of which is incorporated herein by reference in its entirety. Kits useful in the methods of the present invention comprise at least some of the components already described herein, including for example, a container, a first substance and a readily dissolvable film. In one embodiment, the readily dissolvable film contains the 25 first substance. In an additional embodiment, the first substance and the readily dissolvable film are separate. The kits may optionally contain one or more of the following components previously described herein: reagents; reaction components; stabilization components; media components; magnetically responsive particles; and materials that reversibly bind the nucleic acid. Optionally associated with such kits can be a notice in the form prescribed by a 30 governmental agency regulating the manufacture, use or sale of the products, which notice reflects approval by the agency for manufacture, use or sale for administration. The pack or kit can be a single unit use of the components or it can be a plurality of uses. 13 The principles of the present invention will now be described by reference to the following illustrative, non-limiting examples. Example ] An experiment was performed to determine the feasibility of incorporating a 5 dissolvable film into a process of detecting a target analyte. In particular, an assay for Chlanydia trachonatis (CT) or Neisseria gonorrhoeae (GC) was performed as described below, and an analysis of the effects of the inclusion of dissolvable films into the process was made. Containers in the form of extraction tubes were provided with magnetically 10 responsive particles in the form of iron particles according to the following techniques: (1) Approximately 8 mg of magnetically-responsive particles were dispensed into multiple extraction tubes by hand (as a control); (2) Approximately 8 mg of magnetically-responsive particles were pipetted into multiple extraction tube by hand, then covered with a dissolvable film in the form of the following commercially-acquired dissolvable films: (a) Listerine Cool 15 Mint @ strips; (b) Listerine Fresh Burst @ strips; and (c) Listerine Cinnamon @ strips; (3) A dissolvable film formed from a dissolvable carboxymethyl cellulose material loaded with iron oxide particles. The density of the iron oxide particles present in the film is on the order of 8.89 mg/1.5cm 2 . This loaded film was then introduced into an extraction tube with a punch/plunger type device. 20 A solution of Potassium Hydroxide (KOH) was dispensed into each extraction tube containing the magnetically-responsive particles. The high pH KOH solution was dispensed by an automated robotic device, namely the BD ViperTM automated extractor device. Urine samples were then dispensed into the extraction tubes, also by the automated robotic device. The urine samples are spiked to a level of 250 CT Ebs - 250 GC parts/ml, and 25 mixed with a high pH solution to lyse the organism(s) of interest contained in the sample, thereby releasing nucleic acid. A second solution with a low pH was added to the sample that binds the released nucleic acid to the magnetically-responsive particles. This solution contained Sulfuric Acid. A magnetic field was applied to the contents of the extraction tube. The automated 30 robotic device brought a pair of opposing magnets into close proximity with the outside of 14 the tube, thereby drawing the complex to the inner periphery of the tube. The automated robotic device then aspirated the contents of the tube, leaving the complex therein, and the magnetic field was removed from the container. The complex was then washed with a 1mM concentration solution containing 0.01% 5 Tween@ 20. After washing, the magnetic field was reapplied to draw the complex to the inner periphery of the tube, and the wash was aspirated out of the tube. An elution buffer solution was then added to the extraction tube, and mixed, to elute the nucleic acid from the complex. The elution buffer solution comprised a mixture based on a combination of KOH and Bicine. The elution buffer was added and mixed by the 10 automated robotic device. The eluted sample nucleic acid was then separated and subjected to the following strand displacement amplification process (SDA). An analyte-specific binding moiety was linked to the oligonucleotide moiety and mixed with the elution buffer mentioned above. The elution buffer containing the target was added to the priming microwells containing SDA primers CTpB4.S2.3, CTpB4.S1.3, or 15 GCINT3.APR1, GCINT3.APL2, adapters ICAdpt.10, GCINT3.R2, or CTAdpt-F5, bumpers GCINT3.BR3, GCINT3.BL2, or CTpB4.B6, CTpB4.B7 and reporter probes MPC-DR, MPC3.FD, or MPC-FD. After 20 minutes at room temperature the mixture was then heated to 72-73* C for 10 minutes. 100p1 of the mixture was then added to a 53.5-54.50 C amplification wells. Specifically, commercially available BDProbeTecTM amplification wells 20 were used. BsoBl restriction endonuclease and Bst DNA polymerase were added to the amplification wells and isothermal amplification was carried out for 60 minutes at 51.2 52.80* C. The amplification process was monitored with a BDProbeTecTM reader, which detected the fluorescent increase associated with reporter probe conversion. The reader 25 produces MOTA (Measure Other Than Acceleration) values based on the detection of the above-described fluorescence during the amplification process. The MOTA values generated for the above-described samples are reported below in Table I and Table II. 15 Table I.

With these criteria in mind, the above reported data indicates that inclusion of the dissolvable film in the process did not 10 significantly inhibit the extraction or amplification of the target sequence in obtaining a positive indication of the presence of the target during the assay. Example 2 An experiment was performed to determine the feasibility of incorporating a dissolvable film into a process of amplifying and detecting a RNA target, namely a SARS 15 Co-V target sequence, as described below. A SARS Co-V positive control tube was used as the target for the RT-SDA assay. 16 The SARS Co-V positive control tube contained SAR Co-V Positive Control RNA Transcript, yeast RNA, and RNase Inhibitor. A negative SARS Co-V control was also used containing yeast RNA and RNase Inhibitor. Each SARS Co-V control tube was rehydrated with 950pl of nuclease-free water and vortexed. 5 A working stock RT buffer was prepared by mixing the primary constituents nuclease-free water, RNase inhibitor, SARS Co-V internal amplification control, reverse transcriptase, KOH and Bicine. The dissolvable film utilized in this experiment was clear carboxymethyl cellulose (without iron oxide). The film was cut into segments of varying sizes and placed into the 10 SARS Co-V RT priming microwells containing nucleotides dCsTP, dATP, dGTP,dTTP, SDA primers SARSrpC, SARfpC, adapters SARSiacadC, SARSmpcadC, bumper SARSCrtB24, and reporter probes MPC-DR and MPC2.FD. Positive or negative control and the working stock RT buffer were added to each of the respective SARS Co-V RT Priming microwells. After the SARS Co-V RT Priming 15 microwells were heated to 48* C for 20 minutes a second buffer primarily composed of Bicine and KOH was added to each reaction. The SARS Co-V RT Priming microwells were then heated to 72-73* C for 10 minutes. 100p of the mixture was then added to a 53.5-54.5* C amplification wells. BsoBI restriction endonuclease and Bst DNA polymerase were added to the 20 amplification wells and isothermal amplification was carried out for 60 minutes at 51.2-52.8* C. The amplification process was monitored with a BDProbeTecTM reader, which detected the fluorescent increase associated with reporter probe conversion. The reader produces MOTA values based on the detection of the above-described reference values during the amplification process. These values arc measured starting 3-7 minutes subsequent to the 25 beginning of the amplification. The MOTA values generated for the above-described samples are reported below in Table III. 17 Table III.

Example 3 An experiment was performed to determine the feasibility of inclusion of a 10 dissolvable film into a PCR amplification procedure, performed as described below. A plasmid construct pUC19-T. vaginalis was used as the template for the PCR process. The film utilized in the experiments was carboxymethyl cellulose. The film was cut into segments of varying sizes and then placed into PCR thermowell tubes, and labeled as set forth below. 15 An array of PCR tubes were set up to perform the following reactions set forth in Table IV. 18 Table IV.

As indicated in Figure 4, the presence of 2 dissolvable film of a size of up to 30mm does not inhibit the PCR process. 5 Example 4 An experiment was performed to determine the feasibility of incorporating a dissolvable film into a process of amplifying and detecting a DNA target, namely a Chlamydia trachomatis (CT) or Neisseria gonorrhoeae (GC) target sequences, as described below. 10 A CT/GC positive control tube was used as the target for the CT/GC Diplex SDA assays. The CT/GC positive control tube contained CT/GC positive control plasmid, salmon sperm DNA, and control dry down diluent. A negative CT/GC control was also used containing salmon sperm DNA, and control dry down diluent. Each CT/GC control tube was rehydrated with 2ml of sample diluent and vortexed. 15 All control tubes were heat lysed at 114*C for 30 minutes. Each control tube was then allowed to cool down for at least 15 minutes prior to testing. The dissolvable film utilized in this experiment was clear carboxymethyl cellulose (without iron oxide). The film was cut into segments of varying sizes and placed into the CT/GC priming microwells containing SDA primers CTpB4.S2.3, CTpB4.S1.3, or 20 GCINT3.APRI, GCINT3.APL2, adapters ICAdpt.10, GCINT3.R2, or CTAdpt-F5, bumpers GCINT3.BR3, GCINT3.BL2, CTpB4.B or CTpB4.B7 and reporter probes MPC-DR, MPC3.FD, or MPC-FD. Positive or negative controls were added to each of the respective CT/GC priming microwells. The CT/GC priming microwells were then heated to 72-73* C for 10 minutes. 25 100 d of the mixture was then added to a 53.5-54.5* C CT/GC amplification microwells. The amplification microwells were then added to BD ProbeTecTM model 1334 reader where an isothermal amplification was carried out for 60 minutes at 51.2-52.8* C. The amplification process was monitored by observing the fluorescence increase associated with conversion of the reporter probed. The reader produces MOTA values based on the detection 30 of the above-described reference values during the amplification process. These values are 21 measured starting 3-7 minutes subsequent to the beginning of the amplification. The MOTA values generated for the above-described samples are reported below in Table VIII (CT) and Table IX (GC). Table VIII.

Insertion of the film directly into the SDA amplification microwells does not inhibit the reaction. Example 5 An experiment was performed to determine if the dissolvable film would interfere 15 with the extraction procedure. An extraction control (EC) is a labeled oligonucleotide included with the extraction mixture. The fluorescence of the label is monitored to determine if the extraction process is successful. Two dissolvable films (containing iron oxide) and two 22 types of iron oxide particles were tested to determine their effect, if any, on the extraction process. Containers in the form of extraction tubes were provided with magnetically responsive particles according to the following techniques: (1) Approximately 9 mg iron 5 particles (particle sample A or particle sample B) dispensed into the extraction tube; or (2) A dissolvable film (film sample A or film sample B) loaded with iron particles at a concentration of 9.9 mg/1.77 cm 2 . Positive control tubes included the fluorescently-labeled extraction control oligonucleotide, while the negative controls contained no extraction control. The remainder of the extraction process was completed as described in Example 1. 10 The fluorescence of the labeled EC oligonucleotide was then measured to determine if extraction was successful. No amplification steps were performed on the samples. The results of the extraction are shown in Tables X (CT) and XI (GC). These tables illustrate an EC metric which utilizes a 0.5 value for positive results. Values below 0.5 are considered a negative result. 15 Table X.

The positive average values recorded for all dissolvable film samples (0.7 and 0.8) indicate a successful extraction process. Example 6 An experiment was performed to determine the feasibility of incorporating the dissolvable film into a process of detecting a target analyte in different types of samples. In 10 particular, an assay for CT or GC was performed as described below. An analysis of the effects of the dissolvable film was made. Four types of samples were used in the present assay: Urine, Sample Diluent, Clinical Urine and Vaginal Swabs. A "Urine" sample is an in-house sample pool collected from healthy donors. "Sample Diluent" refers to a current BD ProbeTecTm sample buffer that is 15 used to rehydrate control tubes as well as the matrix into which swabs are expressed. 24 "Clinical Urine" refers to urine specimens obtained from people who have been diagnoses with a condition or illness. The extraction tubes were provided with magnetically-responsive particles in the form of one of two types of dissolvable films (Sample Film A and Sample Film B) loaded with iron oxide particles at concentrations of 9.7 mg/ 1.77 cm 2 and 10.6 mg/ 2 5 cm2, respectively. The samples were extracted and amplified as described in Example 1. The MOTA values generated for the above-described samples are reported below in Tables XII and XIII. Table XII.

Example 7 An experiment was performed to determine if the magnetically-responsive particles, in the form of iron powder or dissolvable film, would interfere in the process of detecting a target analyte. The experiment evaluated the effect of the dissolvable film in both a SDA 10 monoplex and diplex system. In particular, an assay for CT utilizing Sample Diluent and Urine Pool samples were performed as described below. In a monoplex assay, a universal detector probe is utilized for real-time fluorescence energy transfer detection of a target. A diplex assay utilizes an internal amplification control (IAC) in addition to the detector probe. The LAC is co-amplified with the target DNA to 15 identify samples that may contain inhibitors of the SDA reaction. In the present Example, the extraction tubes were provided with iron particles in the form of free iron powder or a dissolvable film loaded with iron particles at a concentration of approximately 9.0 mg/ 1.77 cm2. The samples were extracted and amplified as described 26 previously in Example 1. Results are shown in Tables XIV and XV. The Tables show "PAT" values. "PAT" refers to Passes After Threshold, an algorithm used in determining positive samples. A signal is timed to a predetermined threshold value, which is then subtracted by the number of passes the BD ProbeTecTM performs. A higher final PAT value 5 indicates the sample reached the threshold resulting in a positive result at a faster rate than a sample with a lower value. A PAT equal to zero is considered negative. Therefore, values above zero indicate positive results. Table XIV.

The 5 positive PAT values indicate successful amplification of the target in both assays. Example 8 An experiment was performed to determine the optimum mixing parameters for the BD ViperTM automated extractor device to insure dissolution of the dissolvable film with the incorporated iron oxide. This allows the target DNA ample time to be bound and captured by 10 the iron particles. This experiment evaluated multiple mixing parameters on the BD ViperTM instrument. The extraction procedures for the present experiment are the same as those described in Example 1 with the modifications described below. Eight different sample conditions were tested, as described in Table XVI. Six duplicate tubes were prepared for each 15 condition. The extraction tubes were provided with dissolvable film containing iron particles at a concentration of 9.8 mg/1.77 cm 2 . The Sample Diluent was then added to the extraction tubes and mixed at a specified volumes and speeds. This experiment was run to eliminate a twenty-second pause in the current BD ViperTM program. The control extraction tubes were exposed to KOH and mixed 5 times. The tubes were then incubated for 20 seconds to allow 20 dissolution. This incubation was followed by one mixing step with a binding acid mixture 28 containing 3.75M sulfuric acid and an extraction control. In the subsequent test conditions the KOH mix and dissolution pause was removed. The mixing speed and number of mixing repetitions were also varied as indicated in Table XVI. The color of the fluid within the sample tips of the BD ViperTM instrument was visually noted. The iron oxide powder is 5 black and the sample diluent clear. Therefore, an acceptable mixing result was achieved when the fluid in the sample tip was completely black, indicating complete mixing. The resulting color in the tips was rated as follows: (0) = Poor; (1)= Fair; (2) = Good; (3)= Very Good.

This condition provided a result of "Very Good" upon visual inspection. 29 Example 9 An experiment was performed to test the optimized parameters described in Experiment 8. Specifically, a CT assay was performed as described below. Extraction tubes were provided with magnetically-responsive particles in the form of 5 either iron powder (Sample Powder A or Sample Powder B) or a dissolvable film loaded with iron particles. Vaginal swab samples were added to the extraction tubes. The samples were mixed as outlined in Experiment 8 (438pl mixing volume for 15 mixes followed by 700ptl mixing volume for 10 mixes) and amplified as described in Experiment 1. Results are illustrated in Table XVII and expressed as PAT scores. 30 Table XVII.

Example 10 An experiment was performed to test the stability of the dissolvable film over one month at varying temperatures. The film was stored at one of three consistent temperature ranges (2-8*C, 15*C and 33*C) for one month. The reagents were removed from storage and 10 tested in extraction/amplification reactions at ambient temperatures. Tables XVIII through XXIII show the results of the CT and GC assays performed on the reagents stored at cach temperature range. The experiments were conducted as previously described in Example 1. Positive (Target) Values measure amplified CT target. Negative (IAC) Values measure Internal Amplification Control fluorescence. Data is recorded as PAT scores. 31 Table XVIII.
