Microswimmers

Caption

Light-driven microswimmers: the material of the swimming body, which measures just under one millimeter in length, is chosen so that it changes shape when exposed to green light. This causes wave-shaped protrusions to form along the swimmer and drive it in the opposite direction when light patterns move over its surface.
