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.

Micro-tool taps forces that shape living tissue

Scientists have created a micro-tool to gauge how minute mechanical forces affect cellular behavior in a 3-dimensional, in vivo-like environment that mimics how tissue actually forms in a living organism. Immunofluorescent sections of cells are visible above, including cell nuclei labeled in blue. (Credit: Wesley R Legant)
