微小流路とレーザを用いたミドリムシの運動制御による物体操作技術の開発

抄録

The need for micro-object manipulation techniques is becoming important in the engineering and medical fields as objects become increasingly miniaturized. Laser manipulation has become an indispensable tool for research in various fields. On the other hand, laser manipulation requires high-power, high-quality infrared lasers, which have poor energy conversion efficiency. Therefore, we aim to develop a micro-object manipulation technique that can be driven by low light energy, using light-responsive swimming microorganisms that are expected to achieve highly efficient energy conversion. First, we conducted experiments using lasers to control the movement of Euglena. Next, microfluidic devices for object transport were fabricated. Finally, we integrated these devices and conducted experiments on object transport by Euglena, suggesting that object manipulation is possible at low light energies.
