Silk Metamaterials


Researchers at Tufts University, US, are investigating new materials manufactured from silk.

By boiling silk cocoons, the scientists are able to extract proteins to build metamaterials, which can manipulate electromagnetic radiation and light in ways not found in nature.

The new materials have future applications in medicine due to their inherent stability. Films manufactured from silk substrates could potentially be used for storing medicines at room temperatures.

Further applications could include the manufacture of health sensors placed inside the body.
