Acoustic tweezers can position tiny objects (page 2)
Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.
"Current methods for moving individual cells or tiny beads include such devices as optical tweezers, which require a lot of energy and could damage or even kill live cells," said Tony Jun Huang, assistant professor of engineering science and mechanics. "Acoustic tweezers are much smaller than optical tweezers and use 500,000 times less energy."
"Acoustic tweezers are not just useful in biology," said Huang. "They can be used in physics, chemistry and materials science to create patterns of nanoparticles for coatings or to etch surfaces."
"Most cells or particles patterned in a few seconds," said Huang.
