Abstract

Highlights Developed PCSD technique for vapor-phase PFAS detection. Achieved an ultralow detection limit of ∼30 pg for trace PFAS identification. Demonstrated a receptor-free detection via calorimetry of physisorbed molecules. Enabled selective detection suitable for real-time environmental monitoring. Showed potential as a sensor platform for addressing PFAS contamination.
