Abstract
Official abstract text for this publication.
The present invention provides a biosensor system comprising a light source, a cartridge adapted to be illuminated by said light source, a light detector adapted for detecting a signal originating from the cartridge, an illumination control means adapted to vary the illumination of the cartridge between at least two different states, a means for generating a first oscillation with a first frequency, and a means for generating a second oscillation with a second frequency, wherein the frame rate of the light detector is triggered by the first oscillation and the illumination control means is triggered by the second oscillation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system comprising: a source for providing an incoming light; a cartridge having a reflective surface and label particles causing an optical inhomogeneity, the cartridge is configured to generate an evanescent wave having a portion scattered due to presence of the label particles in response to illumination by the incoming light; a light detector configured to detect light originating from the cartridge; a controller connected to the source and…
