Tiny tweezers snag living cells
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.

Fruit flies killed by nanoparticles
Microscopy shows a clean foot and leg of a fruit fly (top), and a foot and leg covered with carbon nanostructures (bottom). Adhering nanostructures may have impeded movement, respiration and vision in adult flies but did not appear toxic to fly larvae that ingested it.
