ABSTRACT

 

 We demonstrate Janus micro motor in fluid. The motor consists of magnesium (Mg) particles deposited gold (Au) on the outmost surface. The Janus particle exhibits a directional motion due to the exposed Mg region which generates hydrogen gas in chloride-rich solutions (e.g. seawater) in a long term manner. We manipulate such particles in a way that two particles are connected using linear DNA structures. Through motile observation of the dumbbell-like objects, we identify the force and directional motion of two-particle ensembles.
