Fabrication and Operation of Acoustofluidic Devices - JoVE

Urbansky A. et al., Label-free separation of leukocyte subpopulations using high throughput multiplex acoustophoresis, Lab Chip, 2019, 19, 1406-1416 Technically dynamic acoustic levitation is a form of acoustophoresis, though this term is more commonly associated with small scale acoustic tweezers. Typically sound waves at ultrasonic frequencies are used thus creating no sound audible to humans. This is primarily due to the high intensity of sound required to counteract gravity. Acoustophoresis is a method based on the migration of suspended particles or cells in an acoustic field caused by the acoustic radiation force.

It is the migration of cells or particles with sound. On exposure to an acoustic wave field, radiation force affects particles. Furthermore, continuous flow separation of different particle/cell types is described where both Free Flow Acoustophoresis (FFA) and binary acoustophoresis are utilized. By capitalizing on the laminar flow regime, acoustophoresis has proven especially successful in performing bead/cell translations between different buffer systems.

Acoustophoresis in microfluidic structures has primarily been reported in silicon microfabricated devices. This paper demonstrates, for the first time, acoustophoresis performed in isotropically etched glass chips providing a performance that matches that of the corresponding silicon microdevices. The resonance mode characteristics of the glass chip were equal to those of the silicon chip at acoustophoresis (acoustic manipulation) while the passive method is based on inertial microfluidics (hydrodynamic manipulation). In paper I, acoustic capillary-based cavity resonator was used to study aggregation of silica and polystyrene particles. We found that silica particles show faster aggregation acoustophoresis Henrik Bruus DOI: 10.1039/c2lc21261g In Part 10 of the thematic tutorial series ‘‘Acoustofluidics – exploiting ultrasonic standing waves forces and acoustic streaming in microfluidic systems for cell and particle manipulation’’, we present and analyze a number of scaling laws relevant for microsystem acoustophoresis.
