Dr. Tony Huang, Assistant Professor in Engineering Science and Mechanics, is manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as tiny tweezers can be small enough to place on a chip. While optical tweezers are large and expensive, acoustic tweezers are smaller than a dime, small enough to fabricate on a chip using standard chip manufacturing techniques. Tony is also manipulating live cells without damaging or killing them.
