Spr sensor system

(57) A summary and subject Search of the adjustment for parallel read-out of the SPR sensor array which can detect two or more samples simultaneously, its production method, a measurement assembly, and the above-mentioned sensor system, a measuring method, and activity material, and those use in high processing screening are offered. Solution means The present invention about the SPR sensor system possessing the SPR sensor surface (120) of a large number arranged in the shape of which consists on the plane on a substrate (10, 20) a two-dimensional raster, Thereby, the SPR surface (120) may be guided through a substrate (10, 20) so that the radiation which can generate a surface plasmon may be reflected from the SPR sensor surface (120) in the SPR sensor surface (120) under specific physical conditions in parallel with the above-mentioned plane. The present invention contains further the separating medium (110) for separating each SPR sensor surface (120) from the adjoining surface (120), While the surface plasmon resonance in the SPR sensor surface (120) has not taken place at least by this, So that the radiation (40) guided through a substrate (10, 20) may be reflected in the domain of a separating medium by a different method from the case in the domain for the SPR sensor surface (120). And in the radiation reflected from the separating medium (110) and the SPR surface sensor (120) while the surface plasmon resonance in the SPR sensor surface (120) had not taken place at least, A separating medium (110) and the SPR sensor surface (120) are arranged so that the contrast between a separating medium (110) and a SPR surface sensor (120) can be identified.
