FIG. 1.

On-chip acoustofluidic device. (a) Schematic of the device. It consists of two inlets (sample inlet, buffer inlet) and two outlets (target outlet, waste outlet). Cells and particles are first focused into two acoustic pressure nodes by the standing waves at 5.09 MHz. Then, target microalgal cells (E. gracilis) are focused into the central acoustic pressure node by the standing waves at 2.03 MHz. The target cells are collected at the target outlet while the other cells and particles are damped at the waste outlet. (b) Functionality of the device. (c) Picture of the constructed device.
