振動誘起流れを用いた微小物体回転操作のモデル構築

抄録

Cell rotation is required for three-dimensional observation and attitude control of cells in various fields such as cell biology or medicine. Previously, we proposed a method for three-dimensional rotation of microobject based on vibration-induced flow. Vibration induced flow is a localized flow that is generated around a microstructure when the vibrations are applied to the microstructures. In this paper, we assumed that a microobject is rotating at the center of a vortex flow and constructed a model of horizontal rotation. We also evaluated the validity of the constructed model using microparticles and mouse oocytes. In the future, we will perform design optimization of a microstructures rotations of specific targets by utilizing this model.
