dc.description.abstractIn this study, we have investigated the influence of crystallinity, phase ratio, and heterojunction formation on the sensing performance of ZnO/ZnFe2O4 (ZnO/ZFO) nanocomposite-based electrochemical sensors for the detection of furazolidone (FZD) antibiotic drug. Results obtained show that the crystallinity and phase ratio of ZnO/ZFO nanocomposites have decisive effects on their electron transfer and active site density. Tuning the crystallinity and ZnO content of ZnO/ZFO nanocomposites is an effective way to enhance the FZD electrochemical sensing performance. Findings from this research suggested that the formation of ZnO/ZFO heterojunction could significantly improve their electrochemical responses for FZD due to arising of the internal electric field and redistribution of Zn2+, Fe3+ cations. Under optimized conditions, the ZnO/ZFO-2-based FZD electrochemical sensor reached an electrochemical sensitivity of 0.78 μA μM−1 cm−2 with a LOD of 0.65 μM in the detection range of 1–100 μM. In addition, all these ZnO/ZFO nanocomposites-based electrochemical sensors offer satisfactory repeatability, selectivity, long-term stability, and practical feasibility in pork and shrimp samples. The insights obtained will benefit the future design of ZnFe2O4 nanomaterial-based high-performance electrochemical sensors for monitoring residual antibiotics in real food samplesvi
