We developed photo-catalytic micromotors, and employed either individual micromotors in peroxide or larger assembled chains under magnetic guiding for microplastics removal. The first removal strategy works through non-selective phoretic interactions of the catalytic swimmers that lead to large patterned passive structures around individual photocatalytic microswimmers. The fact that we can use a wide variety of materials with random properties shows the robustness of these phoretic attraction. However, for the here used system the phoretic interactions have the drawback that the presence of low concentration of peroxide is required, which is it not ideal for many water cleaning applications.
