为了在碳水化合物检测中应用，制备了镍掺杂硼金刚石电极。该电极对碱性介质中1mm葡萄糖产生了定义明确且可重复的伏安图。电极经超声处理后仍表现出良好的电化学稳定性和较低的背景电流，表明镍与碳的结合较强。这些结果表明，Ni-DIA在碳水化合物和氨基酸的检测中具有广阔的应用前景，因此，离子注入作为表面修饰方法对控制多晶金刚石薄膜的电化学性能是有效的。
Nickel-implanted boron-doped diamond electrodes (Ni-DlA) were fabricated in view of their application for carbohydrate detection. This electrode produced well-defined and reproducible voltammograms for 1 mM glucose in alkaline media. The electrode exhibited excellent electrochemical stability with low background current even after ultrasonic treatment, indicating the strong bonding of nickel with carbon. These results indicate the promising use of Ni-DIA for the detection of carbohydrates and amino acids, and thus, an application of ion implantation as the surface modification method is effective for controlling the electrochemical properties of polycrystalline diamond thin films.
