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. They can also manipulate live cells without damaging or killing them. Above, the interdigital transducers (yellow) emit surface acoustic waves that push particles into position.

PENN STATE (US)—Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now researchers have developed a system that uses sound as a tiny tweezer small enough to be placed on a chip. Continue…
