Preliminary Investigation of Bio-carriers Using Magnetotactic Bacteria

This paper proposes a novel micro-carrier based on magnetotactic bacteria (MTB). To confirm the feasibility of such carriers, the thrust force of the bacteria is evaluated. By measuring the swimming speed of MC-1 bacteria in an unbounded medium, a thrust of 4 pN generated by a single MC-1 bacterium is found. The effects on the MTB's swimming speed under the control of micro-electromagnets and influenced by the wall effects when each MTB is attached to a microbead are investigated
