| Outline of Final Research Achievements |
In this study, we evaluate three-dimensional (3D) flow induced around vibrating microobject. And also, we propose 3D cell manipulation method based on observed 3D vibration-induced flow.
We developed 3D observation system of microflow in microfluidic device. We succeeded in observing 3D microflows induced around vibrating microobject. Especially, we found that the flow around miropillar were different when we apply circular and rectilinear vibrations. Furthermore, we applied this flow to 3D manipulation of cells. As an example of 3D manipulation, we demonstrated 3D rotation of microparticles. We succeeded in rotating a microparticles with size of 70 um, in horizontal and vertical directions, by changing directions of applied vibrations.
