Graphene on toast, anyone?

Rice University scientists experimented with various materials to create highly conductive laser-induced graphene, a foamy variant of the one-atom-thick form of carbon. Graphene burned into food could be used as radio-frequency tags for tracking or sensors to warn if the food is contaminated, according to Rice chemist James Tour.

Rice scientists who introduced laser-induced graphene have enhanced their technique to produce what may become a new class of edible electronics.
