Abstract
Official abstract text for this publication.
A device for monitoring radiation emitted by luminophores present in an analyte fluid of a wiregrid biosensor. The monitoring device comprises a non-polarized light source ( 41 ) for illuminating the wiregrid biosensor for exciting fluorescent labels arranged in the analyte fluid of said biosensor. A detector ( 71 ) detects radiation emitted by the labels after excitation. A polarizing filter ( 53 ) is arranged in between the transparent substrate and the detector for suppression of background emission radiation from labels positioned outside apertures in the wiregrid, in the analyte fluid.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for monitoring radiation emitted by luminophores present in an analyte fluid, comprising: a biosensor having at least one non-transparent material arranged on a first side of a substrate of a transparent material and forming at least one aperture for being filled with said analyte fluid, the aperture having a first in-plane dimension which is smaller than half an effective wavelength of radiation in the biosensor and a second in-plane dimensio…
