Self‐Propelled Micromotors Driven by the Magnesium–Water Reaction and Their Hemolytic Properties

Get your motor running: A hemocompatible Mg/Pt Janus micromotor is propelled by hydrogen bubbles generated by the magnesium–water reaction (see picture). Aqueous NaHCO3 reacts with the Mg(OH)2 passivation layer on the Mg surface to form water-soluble MgCO3 and expose the active metal. Since the micromotor is biocompatible, it has potential applications in drug delivery and cell separation.
