In this paper, we study the ultrasonic manipulation of micro/nano in an ultrasonic standing wave field. Starting from the forces acting on particles in stationary standing wave field, we studied the factors affecting ultrasonic manipulation of micro/nano particles within the fluidic medium. Based on analyzing particles’ motion in an ultrasound – gravity coupled field, we proposed and discussed a new application using ultrasonic manipulation of particles to categorize different kinds of micro/nano particles in fluidic medium.

Ultrasonic Standing Wave

Acoustophoresis is the technology to separate the microparticles and cells from suspending fluid. This research focuses on the separation of nanoparticles from water by using macro-scale fluidic separator which works based on gravity-aided ultrasonic standing wave technology. Titanium dioxide particles of 40 nm diameter were concentrated by the combination of ultrasonic standing wave field at 2.2 MHz and gravity-aided sedimentation. The purpose of this study is to investigate the performance of gravity-aided ultrasonic particle to concentrate nanoparticles. It was found that the separation efficiency is 83% at a flow rate of 0.1 mL/min. FEM simulations were also conducted to evaluate characteristics of variation of acoustic energy inside the fluidic channel. Results indicate that nanoparticles can be concentrated using gravity-aided ultrasonic standing wave field, however optimization of the design of the fluidic channel is required for increasing throughput of the separator.
