This work reports about the sensing and biosensing applications of a novel screen printed electrode (SPE) modified by nanostructured nickel oxide thin films obtained by reactive magnetron sputtering under an oblique angle configuration. Using these films as electrodes we demonstrate their ability to detect hydrogen peroxide under neutral pH conditions. Furthermore, as a proof-of-concept, NiO-modified SPEs have been developed and their cholesterol biosensing properties determined by cyclic voltammetry and chronoamperometry.

这项工作报告了一种新型的丝网印刷电极（SPE）的传感和生物传感应用，该丝网印刷电极是通过在倾斜角配置下通过反应磁控溅射获得的纳米结构的氧化镍薄膜进行改性的。使用这些膜作为电极，我们证明了它们在中性pH条件下检测过氧化氢的能力。此外，作为概念验证，已经开发了NiO修饰的SPE，并通过循环伏安法和计时电流法确定了它们的胆固醇生物传感特性。
