Project uses nanotubes to sniff out heavy metals

A team of researchers from Arizona State University and Motorola Labs has developed sensors based on carbon nanotubes, microscopically small structures that possess excellent electronic properties. In early tests, the new devices detected the presence of heavy-metal ions in water down to partsper-trillion levels.
