Abstract Surface-enhanced Raman scattering (SERS) is a spectroscopic technique that utilizes nanostructured substrates and vital in food analysis. However, enhancing SERS substrates’ sensitivity applicability remains challenge. The conductive metal organic framework Ni 3 (HHTP) 2 has been widely used due to its excellent conductivity porous structure. This study combines ’s charge transfer properties with AgNPs’s localized surface plasmon resonance create highly sensitive substrate. Firstly, rod-shaped was prepared, then monolayer of AgNPs film loaded on surface. substrate can detect crystal violet at concentration 10 −14 M, flat structure, coupled film, provided good detection uniformity (Relative Standard Deviation, RSD = 10.09%). Moreover, the successfully detected additives solutions, as well pesticide residues fruit surfaces by bending. offers rapid monitoring solution for safety, facilitating real-time contaminants daily life.
