Abstract
When high-frequency circular vibration is applied to a micropillar in fluid, flow is generated around the micropillar. In this research, we propose an innovative system of oocyte transportation by using vibration-induced flow. It is integrated on a chip with on-chip probe and force sensor for mechanical characterization of oocyte. This system enables us to measure the mechanical property of oocyte in open chip environment. As a result, the bubbles on the chip can be eliminated easily. Moreover, loading and picking up of oocytes is easily done by using conventional mechanical micromanipulator. In this paper, we constructed on-chip transportation and mechanical characterization of oocyte, and demonstrated effectiveness of our proposed method by experiments.
