Platinum playing its part in super-fast nanomotors 30th October 2008

Abstract:
Scientists are making huge advances in developing special nanotubes which make use of platinum as they target tumour cells or clogged arteries in the body, it was reported yesterday (29th October).

Nanomotors, as they are more broadly known, can move forwards through liquid, transporting pharmaceutical agents to specific areas or facilitating the movement of specimen molecules via microchip.

The best-performing of these is a tiny catalytic nanotube which contains platinum at one end and gold at the other and is propelled through a medium that contains the fuel it needs, which is often hydrogen peroxide.

Previously, it could attain speeds of ten to 20 micrometres per second, but now a team led by Joseph Wang at the University of California and Arizona State University has made rapid improvements.
