Acoustic focusing and separations is a growing field of research since it is an efficient and continuous method for particle manipulation in microfluidic systems. Using microfabrication, microfluidic devices driven by an acoustic resonator were used to focus various microparticle suspensions. By simple tuning of frequency, amplitude, and channel geometry, controllable focusing patterns and alignments were obtained. This approach afforded the separation of particles of contrasting sizes, shapes, densities, porosities, and compressibilities. In this study we present the method for the fabrication of these lab-on-chip devices and report on their performance in the manipulation of microsized particles.
