    Researchers are using high-resolution printing technology and the unique properties of graphene to make low-cost biosensors to monitor food safety and livestock health.

    It turned out the sensors — printed with high-resolution aerosol jet printers on a flexible polymer film and tuned to test for histamine, an allergen and indicator of spoiled fish and meat — can detect histamine down to 3.41 parts per million.
