PIXEL DEVICE FOR BIOLOGICAL ANALYSIS, CMOS BIOSENSOR AND CORRESPONDING FABRICATION METHODS

摘要

The invention relates to a pixel device (10) for biological analysis, comprising a photosensitive layer (20), a capture mixture (12) for capturing target proteins, arranged on an external surface of the photosensitive layer and comprising a probe protein (14) grafted to a hydrogel (16, 18), means for collecting photoelectrons in the photosensitive layer, and means for reading and processing an electrical quantity provided by the collecting means, in order to provide a value characteristic of a light intensity detected by the photosensitive layer.
