Patent ID: 7372026

Claim:
A microfabricated cantilever detection system comprising: a first hollow, temperature sensitive, bimorph, microfabricated cantilever forming a reaction chamber, the first microfabricated cantilever having a plurality of laterally disposed projections for receiving light from a light source; a first device, including a light source for directing light to the projections and a light detector, operable to detect a position of the microfabricated cantilever, wherein the first device is operable to determine the position of the microfabricated cantilever; a second device operable to reposition the microfabricated cantilever; a second hollow, temperature sensitive, bimorph, microfabricated cantilever forming a reaction chamber, the second microfabricated cantilever having a plurality of laterally disposed projections for receiving light from a light source, the projections of the first microfabricated cantilever lacking interdigitation with and being spaced from the projections of the second microfabricated cantilever; a third device, including a light source for directing light to the projections of the second cantilever, operable to detect a position of the second microfabricated cantilever, wherein the third device is operable to determine an offset in the position of the second microfabricated cantilever; and a fourth device operable to reposition the second microfabricated cantilever.
