We present a novel 3D cell rotation method based on a vibration-induced flow. By applying circular vibration to a microchip having micropillar patterns, local flow is induced around each micropillar. Thus, we can induce the rotational flow when we pattern three micropillars in triangular configuration and the rotational flow can be utilized for rotational manipulation of cells. Additionally, we can achieve the rotation in vertical direction by applying circular vibration in vertical direction. Furthermore, we integrated polarizing microscopy to the rotation system for label-free observation of internal structure of oocytes. We succeeded in rotation of oocyte with 63.7 degrees/s and demonstrated polarizing observation of oocyte.
