Watching the Nanotubes

Nanotubes perform for the cameras

All it takes is an optical microscope and a video camera to film carbon nanotubes being jostled by water molecules, researchers have found.

The discovery could provide biologists with a relatively cheap and simple way to study how nanotubes interact with living cells and DNA.

Doctoral student Rajat Duggal of the Carbon Nanotechnology Laboratory at Rice University in Texas, US, came up with the idea while studying DNA fragments under an optical microscope. He realised the technique could be applied to carbon nanotubes
