Domesticated Viruses!

Researchers at MIT have engineered a virus so that proteins on its outer coat will bind to cobalt oxide. A paper in the journal Science, reported here describes how the viruses then arrange themselves in a linear fashion forming a wire 6 nanometers in diameter and 800 nanometers in length. With a little gold mixed in, the nanowires can function as conductors in miniature batteries. Nanotechnology Science Virus
