Micromotors: Trajectory Control of Self-Propelled Micromotors Using AC Electrokinetics (Small 42/2015)

Three-dimensional control over the motion of self-powered Janus micromotors is demonstrated by T. Honegger and co-workers using AC electrokinetics, by applying AC electric fields on transparent indium-tin-oxide electrodes. On page 5630, they show how micromotor direction can be regulated for single or collective motion, applicable to in vitro cell manipulation or drug delivery by chemically modifying micromotors without complicated equipment.
