Background, Motivation and Objective In prior research, separation of particles or biological cells in liquids has been accomplished using a balance of ultrasonic forces and viscous drag forces, which depends on particle size and acoustic contrast. Recent work by two groups has exploited surface acoustic waves launched into tilted microfluidic channels for particle or cell separation. While this approach has been effective there is significant fabrication complexity. Here we demonstrate a similar tilted-channel approach using machined channels in PMMA (poly (methyl methacrylate)) and PZT (lead zirconate titanate) wafer excitation.
