Graphene Sensor Detects Substances, Boosts Food Safety
HANGZHOU, China, Dec. 7, 2018 — A new sensor design makes use of the optoelectronic properties of graphene to enable simultaneous detection of multiple substances, including bacteria and other pathogens. The design is based on 2D graphene sheets, each just one atom thick, and was created by researchers at China Jiliang University. Using theoretical calculations and simulations, the researchers designed an array of nanoscale graphene disks. They introduced a small circular defect — an off-center hole — into
