a way to create these coiled nanotubes on a large scale. "The problem we have faced in the past is producing enough of these coiled carbon nanotubes at a reasonable cost to make a difference," said Rao. "Because our current method produces coiled nanotubes...

material needed to be highly conductive; material for cathodes usually needs to be highly insulating. However, the scientists were able to "coax" the M13 virus--modifying two genes-- into binding with iron phosphate first, and then binding with carbon nanotubes....
