Nanosys of Palo Alto, Calif., has received US Patent No. 7,910,064, "Nanowire-based sensor configurations." The patent claims nanowire-based molecular sensors and methods for detecting analytes in a microfluidic system. The methods include detecting changed electrical parameters associated with contact of a nanowire with the analyte in the system. According to the patent, the sensors are mounted in microchambers of the system in electrical contact with the detector, allowing electrical parameter changes induced in the nanowire by the analyte to be monitored.
