Integrated fluorescence detection

摘要

An integrated fluorescence detector (100) for detecting fluorescent particles is described. The integrated fluorescence detector (100) comprises a substrate (110), the substrate (110) comprising an integrated detection element (112) for detecting fluorescence radiation from fluorescent particles upon excitation of the particles with incident excitation radiation. It also comprises a sensing layer (130) adapted for accommodating fluorescent particles to be sensed. The detector (100) furthermore comprises a photonics crystal layer (120) arranged in between the sensing layer (130) and the substrate (110), the photonics crystal layer (120) comprising absorption material and being designed such that the photonics crystal layer is being configured for diffracting incident excitation radiation into a lateral direction in which the photonics crystal layer (120) extends for incident excitation radiation having a wavelength in a wavelength range spanning at least 10nm around the predetermined excitation wavelength.
