Interfacial chemistry governs SERS detectability of trimethoprim and ketoprofen: adsorption geometry and chloride-mediated activation

Year: 2025

Type: article

Abstract: M. Real-sample validation demonstrated reliable recoveries of TMP (89-96%) and KTP (88-95%) in spiked tap water and commercial pharmaceutical tablets, despite matrix interferences. These obtained results highlight the decisive role of adsorption chemistry in SERS detectability and demonstrate that interfacial modification with chloride can extend SERS applicability to weakly adsorbing pharmaceutical pollutants, offering a sensitive platform for environmental monitoring and pharmaceutical quality control.
