Tufts University scientists have shown that it is possible to design biologically active, biodegradable optical devices - made from silk and needing no refrigeration - with applications in medicine, health, the environment and communications. For example, edible optical sensors could detect harmful bacteria in produce, and be consumed right along with the food if it were safe.
