Abstract

Sound fields exert forces on particles suspended in liquids - seemingly without contact. Control over the sound pressure in 3D lets us create force landscapes, where microparticles can be remotely pushed to form larger objects in a single step. We developed the acoustic hologram, a technology that enables such control over ultrasound fields and which shows promise for a new type of biofabrication.
