Dancing lasers levitate carbon nanotubes

Carbon nanotubes have been picked up and moved with a laser beam for the first time. The trick may make it easier to build nanotube-based microchips.
The “optical trapping” technique exploits the ability of a laser beam to trap small particles: when the beam moves, the particles move with it.
