非線対称構造の周りの振動誘起流れを用いた細胞操作の切り替え

抄録

In recent years, various cell manipulations are necessary in medicine and cell biology. Previously, we proposed a method of cell manipulations like transportation, rotation, and trapping using the vibration-induced flow. The vibration-induced flow is a local flow that induced around microstructures by applying vibration to a chip with microstructures. In this paper, we analyzed the flow around microstructures which classified into four categories by symmetry. And we succeed to switch the movement of 70 μm particles under different directions of the vibration. In the future, we aim to realize the switch of cell manipulations. In addition to the symmetry of structures, we will analyze the flow that occurs when changing other factors of structures like sharpness and achieve switch of other cell manipulations.
