Summary:

- Researchers have developed molecular nanocages that can remove up to 80-90% of PFAS (per- and polyfluoroalkyl substances), also known as "forever chemicals," from water. PFAS are a group of synthetic chemicals that are difficult to break down and can accumulate in the environment and the human body.

- The nanocages are made from organic materials and can selectively trap PFAS molecules, effectively removing them from water. This is an important breakthrough, as PFAS are a growing environmental concern due to their persistence and potential health effects.

- The use of these molecular nanocages could lead to more effective water treatment methods and help address the problem of PFAS contamination in water supplies, making it safer for people and the environment.
