Abstract

We present predictive modeling and experimental observation of particle migration and focusing in unconventional acoustic microflmdic device architectures. The standing pressure field that drives fluid transport in a resonant ultrasonic droplet generator is also used to retain targeted microparticles from heterogeneous suspensions. Enrichment capability is assessed using two-dimensional (2D) cross-sectional representations of the device. Optimal particle separation is found to occur at cavity resonances corresponding to fluid atomization. Effective separation of suspended 5 and 20 urn polystyrene (PS) beads is demonstrated at flow rates exceeding 10 mL/min.
