| Research Abstract |
At present, enucleation of oocyte is performed using mechanical micromanipulators. High throughput, precise, and efficient enucleation is highly demanded. In this research, we challenged basic technologies of position and orientation control of oocyte as well as continuous and precise enucleation on a microfluidic chip. We proposed position and orientation control of oocyte by using noncontact manipulation of magnetically driven microrobots. We developed a magnetically driven microrobot with microgripper. By using microneedle, we succeeded in making a small hall at the zona pellucida, and enucleated by pushing the oocyte with the microgripper. For continuous and precise enucleation on a chip, we proposed loading mechanism, which can load the oocyte one by one by using gravitational force. Effectiveness of our method was shown by experiments.
