Removing microplastics and nanoplastics from water in a low-cost way
Overview of the purification process: Water contaminated by microplastics (PET). Addition of magnetic nanoparticles functionalized with polydopamine and lipase. A magnet is used to remove nanoparticles contained in microplastics. Credit: Enrique Eisi Thoma Researchers at Brazil’s University of São Paulo (USP) have developed a new nanotechnology-based solution to remove micro- and nanoplastics from water. Their research is published in the…
