TL;DR: Standing surface acoustic wave based “acoustic tweezers” are demonstrated that can trap and manipulate single microparticles, cells, and entire organisms in a single-layer microfluidic chip and will become a powerful tool for many disciplines of science and engineering.

TL;DR: A unique configuration of tilted-angle standing surface acoustic waves (taSSAW), which are oriented at an optimally designed inclination to the flow direction in the microfluidic channel, is introduced and it is demonstrated that this design significantly improves the efficiency and sensitivity of acoustic separation techniques.

TL;DR: A versatile surface acoustic wave technique capable of controlling the intercellular distance and spatial arrangement of cells with micrometer level resolution that is among the first of its kind to marry high precision and high throughput into a single extremely versatile and wholly biocompatible technology.

TL;DR: In this paper, the ultrasonic propulsion of rod-shaped nanomotors inside living HeLa cells is demonstrated, and the nanorod motors can be activated by resonant ultrasound operating at 4 MHz, and show axial propulsion as well as spinning.

TL;DR: A novel microfluidic device for cell sorting in continuous flow using tunable standing surface acoustic waves that is versatile, simple, label-free, non-invasive, and highly controllable.
