Abstract

Acoustic fields offer a versatile and non-contact method for particle and cell manipulation, where several acoustofluidic systems have been developed for the purpose of sorting. Many acoustic sorting systems rely on either standing waves (SW)[1] or travelling waves (TW)[2, 3] individually and require specific exposure times to the acoustic field, fine-tuned by manipulating the bulk flow rate. Due to the temporal nature of these separations, they are rendered inappropriate for use in systems that require a high degree of flow rate control downstream. Herein, we report a flowrate insensitive sizedeterministic sorting system, permitting the continuous separation of 5.1μm, 6.1μm and 7.0μm particles.
