Patent ID: 7812318

Claim:
A system for detecting one or more analytes in a sample using a biosensor, comprising: a biosensor disk, with an outer surface and a layer encoded with a data path capable of being read by an electromagnetic radiation incident upon said layer, said data path encoded with a baseline data that is static; a detector chamber disposed along said data path, said detector chamber having a surface for affixing detector ligands, said surface distinct from said layer encoded with said data path; a detector ligand adapted to bind with an analyte, said detector ligand affixed to said surface for affixing detector ligands of said detector chamber, wherein said detector ligand when bound to an analyte creates a detectable change to said electromagnetic radiation; and a disk system adapted to accept and rotate said biosensor disk, comprising a source of said electromagnetic radiation focused on said layer encoded with said data path of said biosensor disk, and a sensor adapted to detect said electromagnetic radiation returned from said layer encoded with said data path of said biosensor disk and convert said electromagnetic radiation into an electrical signal.
