Single walled carbon nanotubes anchored to gold-coated nanocubes have been used for detecting blood glucose and other biological molecules. Timothy Fisher, Researcher of Purdue University has created biosensor which is anchored to electronic circuitry by a nanotube, which acts as both a tether and ultra thin wire to conduct electrical signals. With the biosensors, continuous monitoring of blood glucose for diabetics and other applications, including basic scientific research to study diseases and biological processes is possible.
