Active photochemically-driven microswimmers show a great potential for the applications of environment remediations, such as the dye-solution degradation.[1] Previous reports focus on the favourable stimuli of visible light for driving microswimmers only show limited propulsion ability.[1] Here, we demonstrate Ag/AgCl-based spherical Janus microswimmers that reveal an efficient propulsion under visible light illumination.[2,3] They can boost the MSD to a remarkable value of 800 um2 (over 8 s) in pure H2O when activated by blue light (λ = 450-490 nm). We also demonstrates the potential of using visible light-driven plasmonic Ag/AgCl-based Janus micromotors in human saliva, phosphate-buffered saline solution, the most common isotonic buffer that mimics the environment of human body fluids, and Rhodamine B solution.
