PFAS (Per- and polyfluoroalkyl substances) are harmful chemicals known for not breaking down easily in the environment and are found in high amounts in drinking water and various contaminated sites.
There is a rising demand for effective methods to detect PFAS, especially PFOA, in environmental samples like surface water.
This study presents a biosensor using human liver fatty acid binding protein that can quickly and efficiently identify PFOA levels in water samples from areas near Loring Airforce Base without needing complex sample preparation.
