Micromotors push 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. The micromotor can also be steered to climb up microsized blocks, demonstrating its ability to move over three dimensional obstacles.

The technology could open up new possibilities for targeted drug delivery, nanomedicine, tissue engineering, regenerative medicine and other biomedical applications.
