    Abstract

    Surface acoustic wave (SAW)-based manipulation of particles is an indispensable tool to manipulate micro/nanoparticle/cell populations owing to its structural simplicity, biocompatibility, non-invasiveness, scalability, and versatility. This paper presents a design method of a SAW-based particle control device containing two pairs of uniform interfingered transducers. A three-dimensional (3D) finite element model is established to simulate and analyze the SAW device, and various sound pressure field patterns are obtained. The particle tracking module of COMSOL software was used to simulate and verify that the particles can be arranged into patterns under various sound pressure field patterns. The proposed design is expected to be applied in tissue engineering, in-vitro cell research, creating 3D bionic tissue structures, and other applications.
