摘要: This study presented an effective and sensitive SERS substrate for rapid detection of thiabendazole (TBZ) in fruit samples. A core-shell gold/silver nanorod (Au@Ag NRs) has been synthesized as a bimetallic SERS-active substrate. The obtained substrate showed an excellent SERS effect because of the tunable plasmon resonance of Au NRs, the significantly enhanced effect of silver, and the bimetallic synergistic effect of Au@Ag NRs. Under optimal conditions, the substrate was used to detect TBZ in fresh apple juice and peach juice with limits of detection of 0.032 and 0.034 ppm respectively. In addition, the recovery rate was within a satisfactory range of 95-101%, indicating that the Au@Ag NRs substrate could be a SERS detection platform for fruit pesticides residues with great development potential.
