Go Speed Racer! Revving up the world's fastest nanomotors
Date:5/1/2008

WASHINGTON, May 1, 2008 In a major step toward a practical energy source for powering tomorrows nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal.

In the new study, Joseph Wang and colleagues point out that existing nanomotors, including so-called catalytic nanomotors, are made with gold and platinum nanowires and use hydrogen peroxide fuel for self-propulsion. But these motors are too slow and inefficient for practical use, with top speeds of about 10 micrometers per second, the researchers say. One micrometer is about 1/25,000 of an inch or almost 100 times smaller than the width of a human hair.

Wang and colleagues supercharged their nanomotors by inserting carbon nanotubes into the platinum, thus boosting average speed to 60 micrometers per second. Spiking the hydrogen peroxide fuel with hydrazine (a type of rocket fuel) kicked up the speed still further, to 94- 200 micrometers per second. This innovation offers great promise for self-powered nanoscale transport and delivery systems, the scientists state.
