Innovative Magnetic Nanoparticles Clean Microplastics from Water

Researchers at the University of São Paulo have developed a low-cost method to remove micro- and nanoplastics from water using magnetic nanoparticles functionalized with polydopamine and lipase. This process allows the nanoparticles to bind with plastic waste, which can then be extracted using a magnet. The method not only removes plastics but also aims to degrade them into reusable components, contributing to sustainable recycling efforts. This innovation addresses the pervasive issue of plastic pollution in water systems.
