Green lines show results of "racing," where images a, b, c, and d represent the tracks left by various types of speeding nanomotors. The winner is "c," a "catalytic nanomotor" composed of gold and platinum nanowires supercharged with carbon nanotubes. Courtesy of the American Chemical Society
In a “major step” toward a practical energy source for powering tomorrow’s 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 journal.
