Detection of pesticide residue using an Fe₃O₄/GO/Ag nanocomposite as a SERS substrate and mechanism investigation.

ABSTRACT: Considering that pesticide residues cause significant harm to health and the environment, it is crucial and urgent to fabricate surface-enhanced Raman scattering (SERS) substrates with high sensitivity to detect pesticide residues. In this study, a three-layer structure of multifunctional Fe₃O₄/GO/Ag nanoparticles (NPs) as an active substrate for SERS was fabricated and comprehensively characterized through X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), elemental mapping, and X-ray photoelectron spectroscopy (XPS). The active substrate was used to detect thiram pesticide through SERS. Combined with the synergistic effect, Ag NPs and graphene oxide (GO) possessed high-density an
