Scientists have built microscopic, light-powered robots that can think, swim, and operate independently at the scale of ...

Stewart Mallory, assistant professor of chemistry and chemical engineering at Penn State, leads a research group that studies active matter, specifically the collective behavior of self-propelled ...

Scientists at ETH Zurich have developed a new approach for targeted drug delivery inside the human body. They have created tiny particles that can carry medicines directly to their intended ...

Physicists show how microscopic particles can harness fluctuations and external forces to minimize transport energy and even extract usable work. A particle (red sphere) is guided from left to its ...

Scientists have created robots smaller than a grain of salt that can sense their surroundings, make decisions, and move ...
