Scientists have reported a graphene sensor they say costs a buck and can detect dangerous bacteria and heavy metals in drinking water. The sensor uses a GFET — a graphene-based field effect ...

Kim’s group normally inserts a monolayer of graphene between ... An uncooled sensor this sensitive could slash both weight and cost. “This film could be laminated directly onto curved eyeglass ...

Making graphene's electrons oscillate in different ways makes it possible to "read" all the vibrations of the molecule on its surface. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

"Passing a laser beam over the ink transforms it into a form of porous and conductive carbon called 'laser-induced graphene' (LIG). So far, we believed that it was possible to obtain this LIG only ...

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