Micromotors push around single cells and particles

A new type of micromotor -- powered by ultrasound and steered by magnets -- can move around individual cells and microscopic particles in crowded environments without damaging them. In one demonstration, a micromotor pushed around silica particles to spell out letters. Researchers also controlled the micromotors to climb up microsized blocks and stairs, demonstrating their ability to move over three dimensional obstacles.
