Patent ID: 7289207

Claim:
An integrated optical biosensor comprising: a first enclosure; a pathogen recognition surface, including a planar optical waveguide and grating located in said first enclosure; an aperture in said first enclosure for insertion of sample to be investigated to a position in close proximity to said pathogen recognition surface; a second enclosure releasably attached to said first enclosure; a laser in said second enclosure including mechanical adjustment wheels for aligning and means for modulating said laser, said laser having its light output directed toward said grating; detection means located in said second enclosure and in optical communication with said pathogen recognition surface for detecting pathogens after interrogation by said laser light and outputting said detection; electronic means located in said second enclosure receiving said detection for processing said detection, and outputting information on said detection; and an electrical power supply located in said second enclosure for supplying power to said laser, said detection means and said electronic means.
