通过斜角配置（MS-OAD）磁控溅射一步制备了多孔纳米结构 NiO 薄膜，并用作葡萄糖非酶检测的电极。这些薄膜已通过不同的补充技术进行了彻底的表征，并通过电化学方法确定了它们在基本溶液中分析葡萄糖的性能。这些电极的灵敏度是在正常配置下通过 MS 制备的同等致密薄膜的四倍，并且在灵敏度方面优于通过其他方法制备的大多数镍基电极。最后，对血液中葡萄糖检测的高灵敏度、对常见干扰的不敏感性、长期稳定性和高再现性证实了这些电极在实际分析中的良好性能和可靠性。 (C) 2016 Elsevier Ltd. 保留所有权利。
Porous nanostructured NiO thin films have been prepared in one step by magnetron sputtering in an oblique angle configuration (MS-OAD) and used as electrodes for the non-enzymatic detection of glucose. The films have been thoroughly characterized by different complementary techniques and their performance for the analysis of glucose in basic solutions determined by electrochemical methods. These electrodes presented four times higher sensitivity that equivalent compact thin films prepared by MS in a normal configuration and were superior in terms of sensitivity than majority of nickel based electrodes prepared by other methods. Finally, a high sensitivity towards detection of glucose in blood, insensitivity to common interferences, a long term stability and high reproducibility confirmed the good performance and reliability of these electrodes for practical analytical purposes.
