Microfluidic System for Assessing the Controllability of MC-1 Magnetotactic Bacteria as Carriers in Micro-channels

microfluidics, magnetotactic bacteria, microfabrication, micromanipulation

Abstract:
A novel micromanipulation method using Magnetotactic Bacteria to push micro-objects is proposed. The controllability of MC-1 Magnetotactic Bacteria in micro-channels is verified through microfluidic device with implemented micro-electromagets. After introducation of microfabrication procedure and experiment setups, the simulation and experiment results are given. The experiment results obtained show that the MC-1 can be naviagted in the microchannels with the magnetic flux generated with electric current less than 10mA. The trapping and collection of MC-1 by micro-coil is also assessed. The attachments of Magnetotactic Bacteria to microbeads, drug particles,bio-markers or phage, may have great potential as controlled micro-carriers and microactuators in many applications.
