Molecular 'Velcro' gel removes PFAS from water without fluorinated materials

A new gel-based material developed by University of Florida chemical engineers filters PFAS forever chemicals from water more efficiently than many widely used commercial options. The advance offers a potential new path to filtering out PFAS, which has been linked to health effects including birth defects and some cancers. Importantly, the new material doesn't itself use fluorine to trap PFAS, helping reduce fluorinated chemicals in the filtration supply chain.
