Project Summary: PFAS are currently the most important contaminants of emerging concern due to the prevalent presence in the environment and suspected toxicological effects. Therefore, there is an urgent need for a simple, yet sensitive detection method that would allow the potentially affected communities and water/air monitoring personnel to rapidly verify the presence of PFAS and their concentrations. Here, we propose to develop surface engineered MXene-based electronic devices for rapid, sensitive, and selective detection of PFAS in water and air. A quartz crystal microbalance will be used to evaluate the adsorption behavior of PFAS on surface-engineered MXenes. Sensing performance of the as-fabricated PFAS electronic sensors will be systematically evaluated to determine their response time, sensitivity, selectivity, and durability. A prototype portable system will further be developed for field demonstration of the developed PFAS sensor, contributing to the increasing demand for in-home or onsite water and air quality monitoring.
