UCSB Researchers Claim Tunnel-FET Could Offer Faster, More Sensitive Protein Detection | GenomeWeb

Scientists at the University of California, Santa Barbara, have devised an advanced field-effect transistor that could enable rapid detection of low-abundance biomolecules including proteins.

The device, called a tunnel field-effect transistor, or T-FET, offers significant improvements in speed and sensitivity over conventional FETs and could potentially detect proteins at attamolar levels, Kaustav Banerjee, director of UCSB's Nanoelectronics Research Lab and leader of the project, told ProteoMonitor.
