Motion Control of Daphnia magna by Blue LED Light

抄録

Daphnia magna show strong positive phototaxis to blue light. Here, we investigate the effectiveness of behavior control of D. magna by blue light irradiation for their use as bio-micromachines. D. magna immediately respond by swimming toward blue LED light sources. The behavior of individual D. magna was controlled by switching on the LED placed at 15° intervals around a shallow Petri-dish to give a target direction. The phototaxic controllability of Daphnia was much better than the galvanotactic controllability of Paramecium.
