Patent ID: 8384136

Claim:
A demultiplexed nanowire sensor array for detecting one or more chemical or biological species, said demultiplexed nanowire sensor array comprising: a sensor array, wherein said sensor array comprises (a) a first set of nanowires crossing a second set of nanowires at a non-zero angle to form an array of cross points, (b) an active material between a nanowire of the first set of wires and a nanowire of said second set of wires at a cross point of the array, and (c) a receptor on a portion of the active material at the cross point, electrical properties of said active material at the cross point to be altered by the binding of said species to said receptor, each said receptor specific to detecting a specific chemical or biological species; and at least one demultiplexer for addressing said nanowires and permitting measurement of electrical resistance of each said nanowire.
