Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring ...

A dual-gated graphene transistor designed to operate directly in liquid environments has achieved up to 20 times the signal gain of conventional designs while cutting sensor drift by more than 15 ...

Accurately measuring small shifts in biological markers, like proteins and neurotransmitters, or harmful chemicals in the water supply, can identify critical problems before they have a chance to ...
