振動誘起流れを用いたマイクロ粒子の三次元回転操作

抄録

In this paper, we propose 3D rotation method of a single microparticle by using 2-DOF vibrations. We have proposed cell manipulation method on a microfluidic chip based on a vibration-induced flow. Additionally, we achieved various two-dimensional cell manipulations in previous studies. However, 3-DOF actuator was required in previous study to realize three-dimensional rotation of cells. Vibration-induced flows in vertical direction is already observed when we applied a rectilinear vibration on horizontal plane by using 2-DOF actuator. Thus, we aim to perform three-dimensional cell manipulations without 3-DOF actuator. In this study, we propose three-dimensional rotation method of microparticle by using vibrations on horizontal plane with 2-DOF actuator.
