Micro/Nanomotors for Water Purification.

Self-propelled micro/nanomotors are synthetic machines that can convert different sources of energy into motion; at the same time, they are able to serve innovative environmental applications, e.g., water purification. The self-propelled autonomous micro and nanomachines can rapidly zoom through the solution, carrying catalytic surface or chemical to remove or degrade pollutants in much faster fashion than static systems which depend on diffusion and fluxes. This review highlights the recent progress of MNMs in water pollutant detection and removal applications.
