Abstract

We report a scalable approach to locally augment the pressure field for enrichment of microparticles in a longitudinal acoustic trap. Pairs of pillar arrays oriented perpendicular to the inflow direction comprise 'pseudo walls' that support half-wave resonances corresponding to the array gap width. Particles of supracritical diameter focus to nodes of the resulting acoustic field to enable continuous enrichment at a single prescribed location. Targeted separation and isolation of 10-20 μm polystyrene microspheres is demonstrated.
