Title: Reflective characterization of variable-thickness layers on prisms e.g. for observation and analysis of biological reactions, employs light beam, prism and total internal reflection
Inventor: GUEDON PHILIPPE
IPC: G01N21/55
Filed: 2000-12-13
Abstract: Reflective characterization of variable-thickness layers on prisms e.g. for observation and analysis of biological reactions, employing a light beam, prism and total internal reflection, is new. A collimated light beam projected into a prism undergoes total internal reflection at its base. It illuminates a fixed part of the interface forming a working region of the surface (4) to be characterized. A reflected beam leaves an exit surface. Beam angle is varied to scan the working region, finding an incidence at which reflectivity of part or all of the active zones is minimum. An optimum angle of incidence is determined at which the sensitivity of detection in the active zones is maximum. Incidence is controlled to this angle. Reflectivity is measured by an imaging and detection system with a sensitive area receiving the entire exit beam from the working region. An Independent claim is included for imaging apparatus carrying out the method. It employs a prism (3) of given angle and index of refraction. An afocal optical system (1, 2) illuminates it and the layer as described, varying beam angle over 10 deg  or more. A second afocal system (5) is aligned to pass the exit beam. A detection system with a planar incident surface normal to the beam is employed for analysis. The second conjugation system includes an orifice passing all light from the illuminated surface to the detector surface. The prism angle and index of refraction ensure that when the incident beam is parallel to the axis of the first optical system, the intermediate image of the useful zone forming the object for the second detection system, is perpendicular to its optical axis. A fluid is brought into contact with the sensitive layer. This can contain an analyte bonding with ligands immobilized on the active zones. Variations in reflectivity of active zones is measured as a function of time. Results are used for quantitative characterization of interactions of at least one bonding ligand/analyte pair. The reagents are selected from primitive or transferred oligomers or proteins; from protein fragments, random-sequence oligopeptides, antibodies or their fragments, non-protein antigens, haptenes, agonists or antagonists of natural ligands, cells, biological receptors and oligosaccharides. As ligands, a primitive oligomer and a transferred oligomer are used, having point mutation e.g. in a given position. The analyte used is a fragment of DNA in which mutation is sought at the given position. Reflectivity curves are compared with pre-established curves for the primitive type and the 3 mutations possible at the position. Mutation present in the analyte is deduced in the case where a mutation is presented at the position.
