A new active metasurface, the electrically-programmable graphene field effect transistor (Gr-FET), from the labs of Sheng Shen and Xu Zhang in Carnegie Mellon University's College of Engineering ...

and graphene. Yet, despite their potential, FET-based sensors still face a significant challenge: they struggle to detect multiple pathogens or biomarkers simultaneously on the same chip.

Graphene field-effect transistors with ultra-sensitive characteristics are integrated and arrayed, and using a bio-inkjet printer, individual transistors are modified with multiple types of antibodies ...
