  • SPR Surface Plasmon Resonance
  • the well consists of an actual reaction space 2 and a prism 3. Both are made of transparent plastic, e.g polystyrene, by compressing into one unit.
  • a layer 4 of a material capable of generating the SPR phenomenon is attached to the inner surface of the reaction space 2 which also forms one boundary surface of the prism 3 incorporated with the well.
  • This may be a thin film of gold evaporated or sputtered onto the surface.
  • the outer surface of the layer 4 may be formed of a thin additional layer of dielectric material (e.g. polystyrene, glass or diamond) which protects the actual material of the layer 4 and improves attachment of a biomolecule.
  • a biomolecule like antibody, antigen or peptide to attached to the outer surface of the material layer 4, with which the analyte molecule in the sample specifically binds. Coated in this way, the well can be stored in a dry place for a long time.
  • the measurement is performed so that a sample is injected into the well and it is allowed to react with an immobilized molecular layer on the surface of the layer 4.
  • a p-polarized light beam or a luminous beam is incident through the prism 3, which forms the bottom of the well, on the material layer 4 at the boundary surface between the prism 3 and the reaction volume 2.
  • Light is totally reflected back into the prism at the boundary surface at values of the incident angle higher than a specific limiting value of the incident angle provided that the refraction index of the material of the prism 3 is higher than that of the liquid in the reaction space 2.
  • a so-called surface plasmon resonance is observed in the totally reflected light and then the reflected light disappears.
  • the prism 3 forming the bottom of the analysis well 1 can be regarded as a part with a boundary surface 3a, through which the light beam enters the prism, a boundary surface, at which light is totally reflected back into the prism, and a boundary surface 3b, through which the totally reflected light beam leaves the prism.
  • the prism 3 may have a shape of a semicylinder (Fig.1a) or a conventional triangular prism (Fig.1 b) in which case its boundary surfaces 3a and 3b, through which the light beam enters and exits, come closer to each other at the bottom side of the well forming either an apex of a triangle or together a semicircle.
  • the prism may also be a part of aforesaid in which case the outer surface of the bottom of the analysis well is straight being located between the above boundary surfaces 3a, 3b, in other words, it is a kind of truncated prism (Figs. 1c and 1d).
  • Fig.le shows a structure of a prism in which the boundary surfaces 3a, 3b are in the middle of the prism structure coming closer to each other in the direction of the reaction volume 2, in other words, forming a kind of notch in the bottom.
  • the incoming light beam, which is refracted at the boundary surface 3a, is reflected from the outer surface of the prism towards the layer 4 either by virtue of total reflection or by a mirror reflection effected by a reflecting surface 3c attached to the outer surface.
  • the light totally reflected from the boundary surface which borders on the layer 4 is reflected in any of the above ways also from the second outer surface again to the second boundary surface 3b whereat it refracts out of the prism.
  • Figs. 2a-2c show the measuring procedure simplified.
  • the light source 5 is a laser or a light emitting diode (LED). Reflected light can be measured with a photodiode serving as the detector 6 if only changes in the intensity of reflected light at a specific angle (Fig. 2a) are measured.
  • Fig. 2b shows introduction of light with an optical fibre 13 in which case the luminous beam diverging from the tip of the fibre can be made collinear with a collimating optics 7. In an analogical manner, the light from the prism can be led into the detector through an optical fibre 14. If the entire resonance curve is recorded as a function of angle, as shown in Fig.
  • a focusing optics 12 can be used between the light source 5 and the prism 3 and the diverging luminous light beam that has undergone total reflection is measured with an CCD array detector 15 of several detectors.
  • the luminous light beam can be collimated with optics 11 , if necessary, and particularly if the array detector 15 is relatively far from the prism.
  • Figs. 2a-c show a separate optics
  • the optics with the prism 3 in which case the lens structures are located on the surfaces 3a and 3b.
  • the prism and the optics can then be fabricated into a unified structure e.g. by moulding.
  • Figs. 1a-e can be considered to represent various possible well row or strip structures as cross-sections corresponding to the longitudinal direction of the row.
  • the light beam from a photodiode 5 (e.g. a laser diode) is divided e.g. with a holographic element 10 and a collimator associated therewith into collinear light beams incident on each prism 3 of the well plate 9 so that the incident angle is the same in each case, Fig. 4a.
  • Each reflected beam has its own light detector 6 measuring the changes that have taken place in the intensity.
  • the diverging light beam from the photodiode 5 is collimated into a collinear beam by an optics 7.
  • the collinear beams are incident on the entire area of the well plate 9.
  • the light that has undergone total reflection with collinear beams is collected by a two dimensional CCD-detector 15 with adjacent detectors, one for each analysis well 1.
  • a two dimensional CCD-detector 15 with adjacent detectors, one for each analysis well 1.
  • the well plates 9 can also be read, as shown in Fig. 2c, by registering the entire resonance curve as a function of the incident angle for each well 1.
  • the optical setup is then the K ⁇ hler illumination known per se.
  • the light beams can be directed to a row of prisms 3 forming a continuous structure from e.g. a row of several light sources 5.
  • the detectors 6 can be in a row and, when a CCD detector 15 is used, it needs to be only a one-dimensional detector. If it is desired to register the entire resonance curve as a function of the incident angle, a setup according to Fig. 2c can be used having a row of light sources 5 and a two-dimensional detector of several detectors as the CCD detector 15.
  • the SPR cuvette and well plate presented here enables a faster determination because no labelling (additional reagents) is needed.
  • the only additional step possibly needed is the washing of the SPR cuvette before measurement for removing the non-specifically bound material.
  • a simple measuring procedure also enables development of cheap portable measuring instruments e.g. for environmental analytics.
  • the light from the light source must be p-polarized. If the light source itself does not have a polarizer, this can be realized by a separate polarizer placed between the light source and the prism shown under the reference numeral 16 in Figs. 2b, 2c, and 4b.
  • the strip or the well plate multiple sample measurement as well as a positive and a negative control sample can be used for checking the result.
  • the strips or the plates may also have separate control coatings in a sealed space for calibrating the measurement.
  • the well strips and the well plates can be fabricated so that their external dimensions are the same as those of existing strips and plates. Thus new dosing and incubation equipment are not needed.
  • the above structures can be fabricated by spray moulding using plastic material of appropriate optical quality, after which the bottoms of the wells 1 can be coated with a SPR material layer 4 using some known technique.
  • the well plate 9 can be manufactured also by moulding from a single piece thereby forming, in a corresponding fashion, prism structures which are parallel with the well rows and which have a constant cross-section.
  • Fig. 5 shows the influence of a NaCI dilution series 300-80 mM on the intensity of the light obtained in the analysis.
  • concentrations of the liquid in the reaction space which borders on the thin layer of gold, has a clear influence on the light intensity.
  • the measurement has been conducted on the downwards sloping part of the curve representing the intensity as a function of the incident angle in which case an increase in the concentration at a specific constant value of the incident angle effecting the SPR phenomenon causes shift of the curve to the right and, at the same time, an increase in the intensity values of the light that has undergone the SPR phenomenon.
  • Fig. 6 shows the influence of binding of a synthetic peptide and HIV antibody on the intensity values.
  • the influence of the above actions and binding between biomolecules on the intensity values of the SPR measurement can be clearly observed and the figure is a good example how the reaction in the reaction space 2 or in several reaction spaces 2 can be continuously monitored in the device according to the invention.
  • the purpose of use of the invention is primarily the monitoring of the reactions between biomolecules and their qualitative and quantitative analysis, the invention can be applied in all kinds of analyses in which a change in the analyte in the reaction space causes a sufficiently clear change in the light that has gone through the prism.
