We have developed a novel passive particle removal system formed by photo-catalytic Au@Ni@TiO2 micromotors and characterized both, the motion of individual particles and assemblied chains in different fuels, namely H2O and H2O2. Two strategies for removal of microplastics and suspended matter have been proposed. Few microplastics were found in recently bought products, but their presence in environmental water samples was confirmed. Both suspended matter and microplastics from personal care products and extracted from open waters could be removed from selected areas by individual micromotors and assembled chains. The removal was caused by phoretic interaction with individual micromotors and shovelling when the chained assemblies were used. The latter system works efficiently independent of the fuelling system: in dilute peroxide solution and water, which provides huge prospect for microplastics removal in practical environment. The greatest challenge for the future is to increase the selectivity and enable the micromotors to recognize microplastics as environmental pollutant in the variety of suspended materials, in order to improve the microplastics removal efficiency.
