Nanocube

Caption

This image, taken with a scanning electron microscope and digitally colorized and enhanced, shows a new precise biosensor for detecting blood glucose and other biological molecules using hollow structures called single-wall carbon nanotubes anchored to gold-coated "nanocubes." The device resembles a tiny cube-shaped tetherball anchored to electronic circuitry by a nanotube about 25,000 times thinner than a human hair.
