Abstract

Extensive research focuses on developing cost-effective, high-performance electrochemical non-enzyme glucose sensors, particularly using nanocomposites of metal oxides and multi-component alloys. In this paper, a batch of nano-flaky Cu_xO decorated CuCoNiFeSi (Cu_xO@Cu/Fe) and CuCoNiSi (Cu_xO@Cu) electrode was developed by melt-spinning following by anodization. According to the results, the sensitivity of Cu_xO@Cu/Fe-25/35 for glucose detection in the lower (0–1 mM) and higher region (1–15 and 15–21 mM) is 2.544, 1.51 and 0.64 mA mM⁻¹ cm⁻², respectively. The limit of detection (LOD) was estimated to be 0.88 μM (signal noise ratio (S/N) = 3). Furthermore, the Cu_xO@Cu/Fe-25/35 possessed various merits, such as excellent selectivity, good reusability, acceptable reproducibility, satisfying long-term stability, and high tolerance to chloride ions. The enhanced performances of the Cu_xO@Cu/Fe-25/35 electrodes are attributable to the feather-like Cu_xO and synergistic effect between Cu_xO and Ni(Fe, Co)₃Si₂. The work provides a new pathway for detecting all glucose density by electrochemical non-enzymatic glucose sensor.

羽状CuxO多组分CuCoNiFeSi合金的高效非酶葡萄糖传感

广泛的研究集中在开发具有成本效益，高性能的电化学非酶葡萄糖传感器，特别是使用金属氧化物和多组分合金的纳米复合材料。本文采用熔融纺丝法和阳极氧化法制备了一批纳米片状CuxO修饰CuCoNiFeSi （CuxO@Cu/Fe）和CuCoNiSi （CuxO@Cu）电极。结果表明，CuxO@Cu/Fe-25/35在较低区域（0-1 mM）和较高区域（1 - 15和15-21 mM）检测葡萄糖的灵敏度分别为2.544、1.51和0.64 mA mM−1 cm−2。检测限为0.88 μM（信噪比(S/N) = 3）。此外，CuxO@Cu/Fe-25/35具有选择性好、可重复使用性好、重复性好、长期稳定性好、对氯离子耐受性高等优点。CuxO@Cu/Fe-25/35电极的性能增强是由于羽状CuxO和CuxO与Ni(Fe, Co)3Si2之间的协同作用。本研究为电化学非酶葡萄糖传感器检测全葡萄糖密度提供了一条新的途径。图形抽象
