- a reactor for microchemical and / or microbiological reactions which comprises a pipette with a dosing approach (DE 196 42 777 AI), a reactive solid phase support with at least one immobilized reaction partner being provided in the pipette near its lower, narrowed end is.
- a reactive solid phase support with at least one immobilized reaction partner being provided in the pipette near its lower, narrowed end is.
- the surface of this elevation is preferably hydrophobic or solvent-repellent on the outside and inside by chemical coating or by a physical structuring or combinations of both (e.g. a self-cleaning surface "seif cleaning surface”).
- the invention is based on the object of specifying a device with the aid of which a large number of different liquid substances can also be simultaneously absorbed from microplates or nanotiter plates, can be dispensed again in the same grid in defined partial volumes if required, and the possibility of carrying out one or more chemical substances or biological reactions in the device itself and a simultaneous absorption of liquid substances of different viscosity should be possible.
- the essence of the invention is that at least in one row, equally spaced capillary cannulas are provided, which are brought into a communicating connection with a chamber to which an overpressure or underpressure can be applied, the capillary cannulas being embedded in a plate and at least the capillary cannula ends on the inside of the pressure chamber a sieve-like membrane is assigned and above each capillary cannula end there is a space for the absorption of a liquid substance, within which there is the possibility of carrying out chemical or biological reactions, the spaces being separated from one another and all the spaces together within those that can be pressurized with overpressure or underpressure Are arranged chamber, wherein the capillary cannulas are designed so that their internal volume is smaller than the volume that can be absorbed by each capillary.
- the present invention permits a highly parallel liquid transfer and the removal of substance, in particular from micro or Namotiter plates of comparable design or comparable containers.
- the proposed device can be used both for solid-phase-coupled syntheses and in particular for liquid-phase syntheses in all variants.
- the decisive advantage of the device is that defined volumes of different viscosities can be simultaneously absorbed and dispensed, a highly parallel and efficient liquid transfer being ensured.
- transfer operations for bioassay applications can be carried out effectively with this device, for example dilution series of library substances in the assay.
- bioassays can also be carried out after washing, introducing the target substance into solution and after photo-cleaving the synthesized library substances.
- Another possible use is the removal of substances for further analysis processes by transferring them into corresponding analysis vessels.
- the integration of bioassay and synthesis made possible by the device also enables software-supported evaluation.
- Figure 1 shows a possible embodiment of the device for receiving and dispensing liquid substances in a longitudinal section.
- FIG. 2b shows a second possible embodiment of parts of the device essential to the invention
- FIG. 2c shows a third possible option for parts of the device essential to the invention
- Fig. 3 shows a preferred embodiment of the device with the formation of spaces of defined volume within which reactions can be carried out; and Fig. 4 shows, by way of example, a lower view of the device, which is provided with cannulas in several rows and columns, the mutual spacing of which is the cavity grid of a titer plate which can be put in place equivalent.
- FIG. 1 shows schematically a possible embodiment of the device in a longitudinal section.
- Capillary cannulas 1, which are equally spaced from one another, are provided in a row, which are brought into a communicating connection together with a chamber 2, which can be pressurized with an overpressure or negative pressure via a connector 8, the capillary cannulas 1, which are in particular designed as steel cannulas, which are inserted into a Plate 3 are inserted and fixed by gluing.
- a sieve-like membrane 4 Depending on the design, ie depending on the size of the perforations provided for the sieve-like membranes 4, it can be achieved in the example according to FIG.
- the assigned capillaries should have a volume of 1 nl to 120 nl.
- any other dimensions with regard to the volumes mentioned are possible, however, in the event that 5 reactions are to be carried out in the rooms, it must be ensured that the respective rooms 5 have a larger volume than the capillary cannulas assigned to them to prevent crosstalk of reaction liquids between rooms 5.
- FIG. 2a shows a first embodiment of parts of the device shown in FIG. 1 that are essential to the invention.
- the spaces 5 mentioned and the sieve-like membranes 4 are through one-piece component 6 is formed, into which a plurality of recesses for forming the rooms 5 are made down to a floor area 61 and the respective remaining floor areas are provided with a perforation 62.
- FIG. 2b shows a second embodiment of parts of the device shown in FIG. 1 which are essential to the invention.
- the spaces 5 are formed by a component 6, into which a plurality of continuous recesses 63 are initially made, which are provided with separate sieve-like membranes 4 on the sides facing the capillary cannulas 1.
- FIG. 2c shows a third embodiment of parts of the device shown in FIG. 1 which are essential to the invention.
- the sieve-like membrane 4 is formed by a continuous membrane which covers all the recesses 63 and is introduced as a network between the plate 3 and the component 6 by gluing.
- FIG. 1 A preferred embodiment of the device with the formation of spaces 5 of defined volume, within which reactions can be carried out, is shown in FIG.
- two one-piece silicon or glass wafers 6a and 6b are provided, in each of which recesses are made congruent down to the bottom area and each have sieve-like membranes 4; 7 are introduced into the remaining floor areas by selective etching, which is known per se and therefore cannot be explained further here.
- the wafers 6a and 6b thus produced are attached to the sieve-like membranes 4; 7 opposite side connected to each other by anodic bonding, gluing or other joining techniques, which are also common methods that require no further explanation here.
- the sieve-like membrane 4 is given a sieve hole width of 10 ⁇ m and the membrane 7 has a sieve hole width of 1 ⁇ m.
- the respective rooms 5, in each of which a reaction is to be carried out, have a volume of 1 ⁇ l in the example and the capillary cannulas 1 have a volume of 100 nl.
- a liquid reaction can be carried out, for example, as follows: Five different dissolved reagents are each taken up in succession with the device by an appropriately set negative pressure and drawn through the capillary-side sieve 4, so that the volume remains in the reaction space. Any further volume taken up is mixed with that in the reaction space during this process. The more fine-pored membrane 7 prevents the liquid from entering the chamber 2. Depending on the materials used for the device, reactions can also be carried out at elevated temperature.
- the chamber 2 which can be subjected to an overpressure or underpressure to be detachable from the plate 3 (as indicated in FIG. 1) or at least openable above the recesses 63 (not shown in more detail) in order to provide a second access option to create the rooms 5, so that the rooms 5, in the case of designs according to FIGS. 1 and 2a to 2c from above, can be filled with an agent, if appropriate, with a second device designed analogously to the device described. Likewise, with the provided opening possibility of the chamber 2, a flooding of the rooms 5 can be realized.
