In this manuscript, we aim to combine the different principles that have been suggested to enhance the capture and degradation of microplastics (Figure ). We studied polystyrene (PS) microparticles, as it one the most common microplastic wastes, typically being used in food packaging, building insulation, electrical and electronic appliances, etc., and is very toxic to the environment. To make this process scale-able, we rely on inherently asymmetric microparticles with autonomous motion. TiO 2 -based Pac-Man-like microspheres were investigated for this purpose, as previous studies had already demonstrated optimal properties in photocatalytic activity and structural asymmetry, achieving a directed motion. Therefore, the proposed system successfully merges the collection and assembly of microplastics based on attractive phoretic interactions and their photocatalytic degradation.
