Bimetallic coreshell nanorods with thioglycolic acid monolayer for highly sensitive and rapid SERS detection of thiabendazole and ziram residues in Prunus Persica peaches

Simultaneous assessment of agrochemical residues in agricultural entities is crucial for ensuring food safety and protecting consumer health. A highly sensitive and stable thioglycolic acid (TGA) based surface modified coreshell nanorod (Au@Ag@TGANR) arrays were developed for simultaneous fungicide detection in peach samples. The developed Au@Ag@TGANRs exhibited superior surface enhance Raman scattering (SERS) performance, enabling the simultaneous examination of ziram (ZIR) and thiabendazole (TBZ) residues in peach samples with detection limits as low as 0.003 and 0.028 ppm and high R
