Self-propelled magnesium based micromotors: synthesis and magnetic steering

In this work the magnesium based Janus micromotors were prepared by an asymmetric coating of Co-Au bilayer on the surface of Mg microparticles. The micromotor could efficiently self-propel in phosphate buffer saline (PBS) with a highest speed of 221 μm·s−1 without any extra additives through the mac...
