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 values of 0.996 and 0.995, for ZIR and TBZ, respectively. Good recoveries of 86.2 to 108.6 % and 80.2 to 105.7 % were also achieved for peach samples, highlighting the effectiveness of the established protocol for accurate and reliable detection of pesticides in fruits. These results suggest that the proposed method could be a valuable addition to current food safety protocols, with potential application in investigating toxic residues in agricultural entities.
同时评估农业实体中的农药残留对于确保食品安全和保护消费者健康至关重要。本研究开发了一种基于巯基乙酸（TGA）的表面修饰核壳纳米棒（Au@Ag@TGANR）阵列，用于同时检测桃样品中的杀菌剂。所开发的 Au@Ag@TGANRs 表现出优异的表面增强拉曼散射（SERS）性能，能够同时检测桃样品中的锌代氨基甲硫基类（ZIR）和噻菌灵（TBZ）残留，检测限分别低至 0.003 和 0.028 ppm，ZIR 和 TBZ 的 R 值分别高达 0.996 和 0.995。对于桃样品，也获得了 86.2%至 108.6%的良好回收率和 80.2%至 105.7%的良好回收率，这突出了所建立的协议在准确可靠地检测水果中的农药方面的有效性。这些结果表明，该方法可以作为当前食品安全协议的有益补充，具有在农业实体中调查有毒残留方面的潜在应用。
