Microrobots Swim Through Vessels, Deform to Snake Through Tortuous Passageways

Inspired by bacteria, the microrobots can swim through fluids and modify their shape so as to pass through narrow blood vessels or intricate structures. The researchers hope that the devices could be useful in delivering drug cargoes to target tissues in the body. Developing a microrobot that can successfully navigate vasculature is a significant challenge, with narrow, winding blood vessels providing plenty of places for a robot to get stuck. To address this, the Swiss researchers turned...
