Ultrasound Propelled Microbots for Drug Delivery

Sound-powered microbots zip to where they’re needed to deliver drugs
“Researchers from the University of Colorado Boulder say they’ve taken the next big step in microbot design, creating a tiny, self-propelled microbot that can deliver drugs quickly and effectively. . . . . The microbot, made from biocompatible polymers, was designed with a spherical cavity in its center that traps air when the bot is submerged in fluid. When the air bubble is hit with an acoustic wave, such as an ultrasound, it vibrates, propelling the tiny robot forward.” MORE WITH VIDEO
