The clip shows flow-free transport and caging of 5-μm beads (green). The yellow beads
are 1-μm tracer particles that are used for tracking the fluid motion. Due to the particlevolume
dependence of the acoustic forces, the smaller beads are not manipulated by
ultrasound at the employed actuation voltage (10 Vpp). Two frames from the clip are
shown in Figs. 4a-b.
