振動誘起流れを用いた微小物体の三次元回転操作

抄録

We have proposed cell manipulation method on a microfluidic chip based on a vibration-induced flow. We achieved various two-dimensional cell manipulations in previous studies. To realize three-dimensional rotation of cells, 3-DOF actuator was required in previous study. However, vibration-induced flows in vertical (Z) direction is observed when we applied a vibration in XY direction by using 2-DOF actuator. Thus, these vertical flow can be applied for three-dimensional cell manipulations. In this study, we propose three-dimensional rotation method of cells by using X or Y vibrations with 2-DOF actuator.
