Na2SO4-induced aggregation of AgNPs/GO for SERS detection of methylene blue in river water and acetamiprid on cucumber peels.
Surface-enhanced Raman spectroscopy (SERS) has emerged as a powerful tool for rapid contaminant detection; nevertheless, challenges remain regarding its high-sensitivity detection capacity and universal applicability toward pollutants in complex matrices. Herein, we report a facile strategy based on silver nanoparticle...
