Abstract
A biosensor system and method of its use for detecting particles on the surface of an integrated circuit is disclosed. The system can include a light source and a plurality of optical sensors formed on an integrate circuit. The particles can be positioned the surface of the integrated circuit whereby the particles can cast a shadow or shadows that reduces the amount of light transmitted from the light source to the optical sensors. The surface of the integrated circuit can include one or more optical sensing areas whereby the presence of one or more particles may significantly or measurably reduce the amount of light incident on one or more optical sensor.
