行動制御したゾウリムシ単体による物体自動搬送作業

抄録

We have been investigating how to use Paramecium for bio-micromachines. Paramecium could be controlled by the weak electrical field by applying their negative galvanotaxis. In our previous paper, we succeeded controlling paramecium very stably. We also succeeded to transport the object by using Paramecium. The transportation efficiency, however, was very bad due to the paramecium’s soft and fluid dynamic round body. Therefore, we have been trying to make the operation tool for paramecium. We succeeded to attach the washer-like shaped operation tool made of polypropylene film again in the last report. Therefore, we are now trying to make an automatic object manipulation system using tool wore Paramecium. In this report, we developed an algorithm for transporting objects for Paramecium which sets a route consisting of 3 points. We tried to transport a minute gel by Paramecium without wearing tool as a preliminary experiment. In this experiment, we succeeded to transport the gel along two lines of the star-shaped target route (8.1mm) using 146 min.
