A breakthrough biosensor detects glucose in human tears at ultra-low concentrations, opening new avenues for wearable health ...

The sensor was able to detect very tiny concentrations of the material. The ion-sensitive field-effect transistors (ISFETs) employed in sensors operate at maximum transconductance — the current ...

The creation of a viable biosensor using living cells and ... cells can be attached close to the “gate” region of field-effect transistors, which generate currents in the presence of small ...

Silicone-based solar cells have become ubiquitous ... they need to be fixed to a conductive channel of a transistor. We developed a field-effect transistor using graphene as a channel and modified ...
