Scientists have demonstrated that it is possible to design biologically active, biodegradable optical devices -- made from silk and requiring no refrigeration -- with many applications in medicine, health, the environment and communications. For example, edible optical sensors could detect harmful bacteria in a bag of produce, and be consumed right along with the food if it were safe.
