Silicon carbide has been proved as a candidate for power and high-frequency devices. In this paper, we show the application of nanocrystalline 3C-SiC as an electrochemical electrode and its electrochemical functionalization for biosensing applications. SiC electrodes show a wider potential window and lower background current than glassy carbon electrodes. The surface can be electrochemically functionalized with diazonium salts, as confirmed by electrochemical techniques and X-ray photoelectron spectroscopy. The nitrophenyl film is used as linker layer to bond DNA molecule to SiC. These results show that 3C-SiC can be an interesting transducer material for applications in electro- and bioelectrochemical applications.
碳化硅已被证明是一种用于电力和高频设备的候选材料。在本文中，我们展示了纳米晶 3C-SiC 作为电化学电极的应用及其用于生物传感应用的电化学功能化。与玻璃碳电极相比，SiC 电极具有更宽的电位窗口和更低的背景电流。表面可以通过电化学技术和 X 射线光电子能谱证实用重氮盐进行电化学功能化。硝苯基薄膜用作连接层将 DNA 分子键合到 SiC 上。这些结果表明，3C-SiC 可以成为电和生物电化学应用中有趣的换能材料。
