Single beam acoustic trapping

Abstract

A single beamacoustic device, with its relatively simple scheme and low intensity, can trap a single lipiddroplet in a manner similar to optical tweezers. Forces in the order of hundreds of nanonewtons direct the droplet toward the beam focus, within the range of hundreds of micrometers. This trapping method, therefore, can be a useful tool for particle manipulation in areas where larger particles or forces are involved.
