要約(英語): Bioactuator from a microorganism is a promising alternative actuator, since bioactuator works in chemical energy and does not require an external driving circuit. We demonstrate mixing of two continuous solutions by ciliary motion of Vorticella canvallaria. We fabricated a Y-shape microchannel and located Vorticella in it. After spontaneous cell adhesion, two solutions were introduced by hydrostatic pressure. One of the solutions contains fluorescent particles with a diameter of 0.5μm to visualize mixing. Vorticella mixed the low diffusion coefficient of particles in the channel. Mixing of the particles progressed as a flow moved downstream. The mixing performance is quantified by characterizing intensity profiles across the flow channel. Cells of Vorticella ranging from 9 to 15 cells provide significant mixing of the solutions in 8,000μm at a flow speed of 40μm/s.
