Abstract (en)
[origin: WO2020015872A1] The invention relates to a diffractive biosensor for selectively detecting biomolecules, comprising a substrate (S) and an optical biograting (BG) arranged on the substrate (S). The biograting (BG) has periodically arranged receptors for the biomolecules, and the efficiency of a diffraction of incident light (L), and thus the intensity of a measurement light bundle (ML) striking the detector (D), depends on a mass occupancy of the biograting (BG) by the biomolecules to be detected. The biosensor has a device (RG, ST1) for generating a reference light bundle (RL) which is oriented towards the detector (D) and by means of which the phase position of scattered light striking the detector (D) can be determined.
