Researchers at the University of Washington and Moscow State University demonstrated the technique by trapping 3-mm glass beads in vortex-shaped beams of ultrasound. By steering the beams electronically, or by simply moving the ultrasound transducer, they directed the beads along complex 3D paths within a water tank and in the bladders of live pigs.
