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, for example, water purification. The self-propelled micro and nanomachines can rapidly zoom through the solution, carrying catalytic surface or chemical to remove or degrade pollutants in a much faster fashion than that of static systems, which depend on diffusion and fluxes. This review highlights the recent progress of micro/nanomotors in water pollutant detection and pollutant removal applications.
