Scientists have developed organic microparticles that can steer through biological fluids and dissolved blood in unprecedented ways. Even in very salty liquids, the microswimmers can be propelled forward at high speed by visible light, either individually or as a swarm. Additionally, they are partially biocompatible and can take up and release cargo on demand. The material properties are so ideal they could pave the way toward designing semi-autonomous microrobots applied in biomedicine.
