Dropping nano-anchor Touch the tines of a tuning fork and it goes silent. Scientists have faced a similar problem trying to harness the strength and conductivity of carbon nanotubes, regarded as material of choice for the next generation of everything from biosensors to pollution-trapping sponges.Fifield reported the group's findings today at the American Chemical Society national meeting. In the decade since the synthesis of the first carbon nanotubes, researchers have attached molecules—intended to be the "feelers" for picking up chemical sensations and passing the information to the nanotube—using techniques that call for strong acidity and other harsh conditions that compromise the material's utility.
