Abstract:
MoS2 NFs@Ag NPs with a three-dimensional flower-like architecture were designed as high-performance SERS substrates for ultrasensitive PFAS detection. Synergistic plasmonic coupling, dense hot spots, and interfacial charge transfer enabled sensitive, morphology-dependent detection of PFOA and PFOS, offering a robust platform for environmental trace monitoring.
