Monodispersed PEG-coated ZnS (P-ZnS) nanoparticles (NPs) were synthesized by facile microwave process and utilized as efficient electron mediators for the fabrication of highly sensitive hydrazine chemical sensor. The detailed morphological and structural properties revealed the monodispersity and good crystallinity for synthesized P-ZnS NPs. A high-sensitivity of ∼ 89.3 μA cm(-2) μM and low limit of detection of 1.07 μM, based on S/N ratio, were obtained for the fabrication of hydrazine chemical sensor based on P-ZnS NPs. To the best of our knowledge, this is the first report which demonstrates the utilization of P-ZnS NPs for the fabrication of efficient hydrazine chemical sensor. By this work, it could be concluded that simply synthesized ZnS NPs can be used as efficient electron mediators for the fabrication of effective hydrazine chemical sensors.
单分散聚乙二醇包覆的 ZnS（P-ZnS）纳米粒子（NPs）通过简便的微波法合成，并被用作高效的电子介体，用于制备高灵敏度的肼化学传感器。详细的形态和结构性质揭示了合成的 P-ZnS NPs 的单分散性和良好的结晶度。基于 P-ZnS NPs 制备肼化学传感器，获得了高达 89.3 μA cm(-2) μM 的高灵敏度和基于信噪比的 1.07 μM 的低检测限。据我们所知，这是首次报道将 P-ZnS NPs 用于制备高效肼化学传感器。通过这项工作，可以得出结论，简单合成的 ZnS NPs 可用作制备有效肼化学传感器的高效电子介体。
