Laser Tweezer Traps Nanotubes

Researchers from Arryx, Inc. and New York University have demonstrated that it is possible to trap and move carbon nanotubes with optical tweezers. This is tricky because nanotubes' diameters are orders of magnitude smaller than the wavelength of light used to move them. The researchers used a wavelength of light that was strongly absorbed by the carbon nanotubes. By strongly focusing the light, the researchers were able to trap the nanotubes.
