赤血球サイズの超小型自己推進マイクロスイマー

抄録

Self-propelled microswimmers have significant potential for medical applications. Our concept uses biofuel cell (BFC) and electroosmotic propulsion (EOP). This EOP mechanism suggests that a smaller body would have a larger velocity. For the larger velocity, we need a design and fabrication method suitable for the body size comparable to red blood cell. We used multiple types of polymer composite layers with different conductivities and the two photon polymerization method, and succeeded in fabricating the smaller prototype and identified its conditions.
