Cool factor: This technology is a long, long way from use in humans, but the researchers get serious credit for dreaming big. Their idea: microrobots smaller than one millimeter that could serve as tiny devices that carry drugs to specific targets. Or they'd serve as a microscopic device with serious muscle, seeking out and destroying tumors directly or smashing through blood clots. Last winter they made a first step toward that goal, testing an external magnetic field to move the microrobots backward and forward or side-to-side while making corkscrew-like motions. They succeeded, steering a microrobot through a mock blood vessel filled with water. The Journal of Applied Physics highlighted their findings.
