In a “major step” toward a practical energy source for powering tomorrow’s nanomachines, researchers at Arizona State University’s Biodesign Institute report the development of a new generation of tiny nanomotors that are up to 10 times more powerful than existing motors.

Just like weekend hot-rodders who tinker with their car engines in the ultimate quest for speed, a research team led by Joseph Wang, who directs the institute’s Center for Biosensors and Bioelectronics, set out to improve on the design of current nanomotors. These so-called “catalytic nanomotors” are made with gold and platinum nanowires and use hydrogen peroxide (the same chemical that bleaches hair) as a fuel for self-propulsion.  Read More...
