In this study, a biosensor, based on a glucose oxidase (GO) immobilized, carbon-coated tin sulfide (SnS) assembled on a glass carbon electrode (GCE) was developed, and its direct electrochemistry was investigated. The carbon coated SnS (C-SnS) nanoparticle was prepared through a simple two-step process, using hydrothermal and chemical vapor deposition methods. The large reactive surface area and unique electrical potential of C-SnS could offer a favorable microenvironment for facilitating electron transfer between enzymes and the electrode surface. The structure and sensor ability of the proposed GO/C-SnS electrode were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), and cyclic voltammetry study (CV).
在本研究中，开发了一种基于固定化葡萄糖氧化酶（GO）、组装在玻碳电极（GCE）上的碳包覆硫化锡（SnS）的生物传感器，并对其直接电化学进行了研究。采用水热法和化学气相沉积法，通过简单的两步工艺制备了碳包覆SnS（C-SnS）纳米颗粒。C-SnS的大反应表面积和独特电势可为促进酶与电极表面之间的电子转移提供有利的微环境。使用扫描电子显微镜（SEM）、X射线衍射（XRD）、拉曼光谱、紫外可见光谱、傅里叶变换红外光谱（FTIR）和循环伏安法研究（CV）对所提出的GO/C-SnS电极的结构和传感能力进行了表征。
