Carbon nanotubes pinned down at last

A new technique that places carbon nanotubes exactly where they are needed could help overcome one of the biggest obstacles blocking the development of nanotube-based electronic devices. The method uses a specially constructed molecule that attaches one end to a carbon nanotube and the other end to a strip of metal oxide that has been placed on piece of silicon. The nanotubes are just a few nanometres in diameter, and knowing exactly where a tube is means researchers can use it to make a transistor.
