Graphene-fed silkworms produce super-strong, electrically conductive silk

You are what you eat, and in the case of silkworms, what they eat may soon influence what you wear.

Scientists were able to produce a stronger silk by adding a water-based solution of graphene onto the mulberry leaves regularly eaten by the tiny creatures. Besides being stronger, scientists also discovered that the new silk had the ability to conduct electricity.

In simplest terms, ecologically-friendly graphene is a thin layer of pure carbon. Carbon, for those who have forgotten, is the second most abundant mass in the human body.

Of course, silk is rarely – if ever – used in the manufacture of security uniforms, but that could change in the future. The findings could set the stage for stronger and more durable smart fabrics, wearable electronics and even medical devices.
