Researchers have engineered a novel solution to one of modern water treatment's most vexing problems: removing PFAS chemicals that contaminate drinking water supplies across the globe.
The new method deploys microscopic cage-like structures designed to snare PFAS molecules, with particular success against short-chain variants that have historically resisted conventional filtration. Laboratory tests demonstrate the technology can purge up to 98 percent of these persistent pollutants from contaminated water.
What sets this approach apart is its durability. The nano cages retain their effectiveness through repeated use cycles, suggesting commercial water filters built on this technology could operate longer before requiring replacement. That durability translates to potentially lower costs and less waste in municipal water systems.
PFAS chemicals, which include thousands of industrial compounds used in everything from nonstick cookware to firefighting foam, earned the nickname
