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 ...

"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 ...
