GU Man-lei,XIONG Mei,YOU Jin-kun,YU Yu-yan,ZHANG Hong-yan.Functionalized Silver Nanoparticles for Visual Detection of Carbendazim in Medicinal Herbs[J].Journal of Instrumental Analysis,2025,44(04):660-666.
In this study,silver nanoparticles(AgNPs) were synthesized using trisodium citrate as a protectant,and
p
-aminothiophenol(PATP) was modified on the surface of AgNPs to establish a method based on the visual detection of carbendazim by PATP-AgNPs. And the concentration of PATP,pH and concentration of buffer solution and reaction time were optimized. The results showed that under the optimal conditions,the limit of detection of carbendazim by the established visualization detection method was 0.052 7 μg/mL,and the concentration of carbendazim showed a good linear relationship in the ranges of 1-3 μg/mL and 3-5 μg/mL. The spiked recoveries of the three actual samples of yam,asparagus and tertiary ginseng were in the range of 91.1%-108% with the relative standard deviations(RSDs) of 1.1%-5.7%. The method has the advantages of rapidity,simplicity and high specificity,and is suitable for the on-site rapid determination of carbendazim in herbs.
