The trapping of particles in acoustic standing waves has long been known and is often demonstrated, for example, by the Kundt’s tube apparatus. However, despite this well-known demonstration few practical applications of trapping in acoustic fields have been demonstrated. In this talk I will review recent work we have carried out using simple, practical devices, that can be used for trapping and manipulation from the millimetre to the micron scale. Examples given will include the acoustic trapping of liquids and the formation of glasses in air, particle and cell trapping and manipulation in water and the formation of micron structured gels from chemical coascervate droplets.
