Fig. 5: Bioinspired microparticle trapping using a combination of + and – ciliary bands.

a Schematic of a bioinspired trapping mechanism consisting of a + ciliary band adjacent to a – ciliary band (see also Supplementary Movie 8). b Image sequence demonstrating microparticles becoming trapped in the – ciliary band, as indicated by red, green, and blue trajectories at 68.5 kHz and 20 VPP. c Expanded spatial trajectories of microparticles that became trapped by the flow field produced from the adjacent + and – ciliary bands. d Plots of microparticle velocity versus y-position: the left panel indicates the source and the right panel the sinking behavior of the trapping ciliary band (Source Data 3 and Supplementary Software 3). Scale bar, 200 μm.
