“Acoustic Tweezers” Use Sound Waves to Control Items

Scientists have developed “acoustic tweezers” that use sound waves to control items regardless of their optical, electrical or magnetic properties, making them noninvasive and very versatile.

By using sound waves to push and pull matter like science fiction tractor beams, scientists have developed “acoustic tweezers” that can manipulate blood cells and microscopic worms on a platform the size of a dime. The dexterous control this device could give researchers tinkering with organisms in microchip-sized laboratories could potentially lead to a wide range of medical insights, the inventors proposed.
