Abstract

In this study, we manipulated the swimming direction of bacteria and controlled the switching off movement by using dc and ac galvanotaxis. The microstructures blotted by Serratia marcescens could be spontaneously manipulated and switched off at the desired position. The optimum ac frequency for switching off the microstructural motion was 7 Hz. We built a mathematical model to analyze and understand the oscillating motion of microstructure.
