Sensitive Electrochemical Detection of Thiabendazole in Fruits Using Ag−MoS2 Electrode

Abstract

AbstractHerein, Ag nanoparticles (NPs) modified MoS2 (Ag−MoS2) was applied to the surface of glassy carbon (GC) to produce a robust electrochemical sensor for the detection of thiabendazole, a common antifungal in the post‐harvesting of fruits. Cyclic voltammetry studies confirmed thiabendazole exhibited an irreversible, diffusion‐controlled process on Ag−MoS2 with a two‐fold increase in peak current than the pristine MoS2. A square wave voltammetry was used for the detection of TBZ. The developed sensor exhibited a linear range between 1–10 μM with LOD down to 0.1 μM (S/N>3). Analysis of TBZ in mango and banana matrices gave a recovery of 91.6–100.4 % indicating the suitability of the sensor for food safety monitoring.
