摘要
Abstract Nano‐/microplastics accumulate in aquatic bodies and raise increasing threats to ecosystems and human health. The limitation of existing water cleanup strategies, especially in the context of nano‐/microplastics, primarily arises from their complexity (morphological, compositional, and dimensional). Here, highly efficient and bio‐based flowthrough capturing materials (bioCap) are reported to remove a broad spectrum of nano‐/microplastics from water: polyethylene terephthalate (anionic, irregular shape), polyethylene (net neutral, irregular shape), polystyrene (anionic and cationic, spherical shape), and other anionic and spherical shaped particles (polymethyl methacrylate, polypropylene, and polyvinyl chloride). Highly efficient bioCap systems that adsorb the ubiquitous particles released from beverage bags are demonstrated. As evidence of removal from drinking water, the in vivo biodistribution of nano‐/microplastics is profiled, confirming a significant reduction of particle accumulation in main organs. The unique advantage of phenolic‐mediated multi‐molecular interactions is employed in sustainable, cost‐effective, and facile strategies based on wood sawdust support for the removal of challenging nano‐/microplastics pollutions.
