Abstract

The invention relates to a device and a method for carrying out quantitative fluorescence immunoassays by means of evanescent field excitation. Various known biochemical assays of general receptor-ligand systems can be used. For this purpose, light of at least one light source is directed at an angle .alpha. onto the boundary surface of two media which have different refractive indices. A light source is selected which emits substantially monochromatic light with a wavelength which is suitable for exciting a marking substance. The light is directed onto the boundary surface which is disposed between an optically transparent base plate made of a material where the refractive index n1 is greater than the refractive index n2 of the material above the boundary surface, and a cuvette-shaped receiving region for the sample. The receiving region is covered with a covering plate on the side disposed opposite the base plate.
Arranged between base plate and covering plate is at least one functional layer and a detector for detecting the fluorescent light being disposed on the same side of the base plate as the light source.
