Acoustophoresis
ACOUSTOPHORESIS (Acoustofluidics)
Using vibrations and acoustic interaction to manipulate particles and liquid sample
Droplet handling
Different functions on samples (on a surface or in channels)
Two kinds of acousto-fluidic interactions :
Low frequency (<100 kHz) standing waves
- Flexural plate waves
- Step by step displacement
High frequency travelling wavesSurface acoustic waves (SAW)
- Acoustic streaming
- Linear and step by step displacement.
- Applications to droplets, sorting particles
