Perfluoroalkyl acids represent a potentially hazardous subset of per‐ and polyfluoroalkyl substances (PFAS). Simple sensors capable of detecting these substances at dilute concentrations are needed to mitigate their environmental burden. Anionic fluorosurfactants were theorized to form multilayers when associating with crosslinked poly(N‐isopropylacrylamide) networks beyond their charge neutralization concentration, presenting electrostatic repulsion between adjacent sheets and enlarged swelling ratios as a possible indicator for the contaminants. The work from Thomas D. Dziubla and coworkers on page 289 evaluates the capability of a simple polymeric detection scheme for PFAS based on crosslinked, thermoresponsive poly( N ‐isopropylacrylamide) (PNIPAM) hydrogels.
