Particle-size-dependent acoustophoretic motion and depletion of micro- and nano-particles at long timescales
We present three-dimensional measurements of particle-size-dependent acoustophoretic motion of micropar- ticles with diameters from 4.8 μm down to 0.5 μm suspended in either homogeneous or inhomogeneous fluids inside a glass-silicon microchannel and exposed to a standing ultrasound wave. To study the crossover from radiation force dominated to streaming dominated motion as the particle size is dec
