Single cell analysis has attracted much attention to reveal the detailed and localized biological information. Local environmental control technique is desired to analyze the detailed and localized properties of a single cell. In this paper, we propose the local environmental control system with nano/micro dual pipettes to control the local reagent concentration dynamically and arbitrarily. Local environmental control by nano/micro dual pipettes is applied to the rotational speed control of bacterial flagellar motor which is a rotary molecular machine. We demonstrate quick-response and iterative rotational speed control of Na+-driven flagellar motor in both accelerating and relaxing directions by switching the local spout between Na+-containing and Na+-free solutions with nano/micro dual pipettes. It is shown that the rotational speed might be controllable by changing the spouting volume of Na+-containing solution with multiplying the DC voltage.
