Oregon State University researchers reported an electrochemical sensor that uses reduced graphene oxide in a nanocomposite designed to speed up food-quality testing. The device was built to detect theobromine in drinks and chocolate milk, pointing to a practical route for lower-cost screening outside conventional labs.
A new Nature Sensors study published on March 31, 2026, describes a self-powered chemical sensor built around graphene, MoS2 and silicon, a design aimed at lowering power demands in compact sensing devices.
Hememics Biotechnologies and General Graphene say they have manufactured more than 100,000 graphene biosensors, marking a manufacturing milestone for a 32-plex diagnostic platform aimed at faster point-of-care testing.
Researchers at the University of Arkansas and the University of Michigan say they have demonstrated the first ultra-low-power temperature sensor powered by graphene-based solar cells, a battery-free design that could reduce maintenance in remote monitoring and wearable devices.
Melexis and Graphenea have expanded their graphene biosensor collaboration with a development kit for evaluating integrated GFET-on-CMOS sensors, a practical step toward chip-scale biosensing systems.
Paragraf has launched a GFET Discovery Kit that packages its graphene molecular sensing hardware into a ready-to-run setup, a practical step aimed at researchers who want to test graphene biosensing without assembling the electronics themselves.
