“Forever chemicals” are notoriously difficult to detect, but a collaboration between the University of Chicago Pritzker School of Molecular Engineering and Argonne National Laboratory has yielded a novel detection method. The method, which they plan to share via a portable, handheld device, uses unique probes to quantify levels of PFAS “forever chemicals,” some of which are toxic to humans.
