Development of The Operation Tool and Attachment Technology for The Microorganisms as Bio-micromachines

If we want to use microorganisms as bio-micromachines, we have to develop operation tools for the microorganisms. For that purpose, we developed operation tools for Paramecia and Daphnia. Both microorganisms can be controlled by their taxis. In the case of Paramecia, we developed a washer-like operation tool made of polypropylene film. It can improve paramecium's object pushing ability by attaching the tool on paramecium. The tool attachment on paramecium, however, was too difficult and we have to develop the easier method in the future. In the case of Daphnia, we can glue operation tool on the Daphnia's shell, so the attachment is much easier than paramecium. We glued a needle on a daphnia's back, and the daphnia could puncture a balloon. We also made a injector for daphnia and attach it on daphnia. This injection installed daphnia could pour a medical fluid into a jelly. These technologies will open the door to use microorganisms as biomicromachines
