An efficient electrode for non-enzymatic glucose detection is produced with low-cost techniques on a Cu wire. ZnO nanorods (NRs) were grown on a Cu wire by chemical bath deposition and were used as the substrate for pulsed electrodeposition of nanostructured Ni(OH) flakes. The effect of the electrodeposition potential on the final morphology and electrochemical behavior of the Ni(OH)/ZnO/Cu structures is reported. ZnO NRs resulted to be well dressed by Ni(OH) flakes and were tested as glucose sensing electrodes in 0.1 M NaOH solution, showing high sensitivities (up to 3 mA mM cm) and long-term stability. The presence of ZnO NRs was shown to improve the performance of the glucose sensor in terms of electrochemical stability over the time and sensitivity compared to Ni(OH)/Cu sample. The reported data demonstrate a simple, versatile and low-cost fabrication approach for effective glucose sensing system within a urban mines framework.
一种高效的非酶葡萄糖检测电极是通过低成本技术在铜丝上制备的。采用化学浴沉积法在铜丝上生长氧化锌纳米棒(NRs),并将其用作脉冲电沉积纳米结构 Ni(OH) 薄片的基底。报道了电沉积电位对 Ni(OH)/ZnO/Cu 结构最终形态和电化学行为的影响。结果表明,Ni(OH) 薄片很好地包裹在 ZnO NRs 上,并将其用作 0.1 M NaOH 溶液中的葡萄糖传感电极,表现出高灵敏度(高达 3 mA mM cm)和长期稳定性。与 Ni(OH)/Cu 样品相比,ZnO NRs 的存在显示出在电化学稳定性和灵敏度方面改善了葡萄糖传感器的性能。所报道的数据表明,在城市矿山框架内,提出了一种简单、通用且低成本的有效葡萄糖传感系统制造方法。
