Detecting biomolecules with nanoscale active electronic devices.

Nanoscale electronic devices offer bio-detection schemes that are complementary to optical detection methods. This paper reviews the utilization of field effect transistor devices with carbon nanotubes as conducting channels -the device architectures and detection schemes are reviewed in the paper 5592-34 presented at this meeting- for the detection and monitoring biological processes such as ligand-receptor interactions and enzymatic processes. A complex device with both biological and electronic functionality is also discussed.
