Abstract
The invention relates to a device for detecting biological materials, comprising a light source (1) that radiates light (2) into an object (5), a photonic crystal brought into contact with the object, a detector (8) that detects light (7) transmitted through the photonic crystal (6) and the object, a first polarization filter (3) arranged between the light source (1) and the photonic crystal (6), and a second polarization filter (4) arranged between the object (5) and the detector (8) and rotated 90° relative to the first polarization filter (3), wherein the source (1) and the photonic crystal (6) are matched to each other such that the resonances caused by the photonic crystal (6) and the resonances caused by the interaction of the photonic crystal (6) with the object (5) lie in an edge range of the emission spectrum of the light source (1).
