A field effect transistor (FET) is a carrier device with three terminals: source, drain, and gate. In FETs, an electric field can be applied at the terminal of the gate, modifying the conductive ...

(Nanowerk News) A new quantum mechanical-based biosensor designed by a team at University of California, Santa Barbara offers tremendous potential for detecting biomolecules at ultra-low ...

Move over, graphene. An atomically thin, two-dimensional, ultrasensitive semiconductor material for biosensing developed by researchers at UC Santa Barbara promises to push the boundaries of ...

Biosensor technology can detect a biological event by the production of a measurable signal. The process of detection combines a recognition element for a type of biomolecule or chemical reaction with ...

The growing field of bioelectronics has the potential to revolutionize personal healthcare, strengthen security systems, and help safeguard the environment, as well as protect food and water supplies.

A light-activated graphene and black phosphorus biosensor detects Alzheimer's biomarkers in blood at zeptomole sensitivity, marking a major advance toward ultra-early, non-invasive diagnosis.
