title = "Acoustic impedance based separation of microspheres using travelling surface acoustic waves",
abstract = "We report on a novel microfluidic separation mechanism for continuous, label free and contactless segregation of polystyrene (PS) and polymethylmethacrylate (PMMA) microspheres based on their acoustic impedances using travelling surface acoustic waves (TSAWs). The separation mechanism is based on the differences in acoustic impedances of the two particle materials. We have provided a theoretical estimation of the acoustic radiation force (ARF) acting on the elastic microspheres to further corroborate the experimental results. The estimated ARF is used to unravel the reason behind unintuitive response of microspheres to the TSAWs where smaller particles are deflected more than the larger particles.",
