Acoustic Manipulation

Definition

Acoustic manipulation refers to the use of sound waves to exert forces on small particles, droplets, or biological cells, enabling precise control and movement without physical contact. This technique leverages acoustic fields generated by ultrasonic transducers, allowing for the manipulation of materials on a micro and nanoscale, making it particularly useful for applications such as single-cell analysis and the development of lab-on-a-chip devices.
