New graphene-based sensor design could improve food safety: Approach offers high sensitivity for detecting gases, chemicals and pathogens

In the US, more than 100 food recalls were issued in 2017 because of contamination from harmful bacteria such as Listeria, Salmonella or E. coli. A new sensor design could one day make it easier to detect pathogens in food before products hit the supermarket shelves, thus preventing sometimes-deadly illnesses from contaminated food.
