Abstract

Designing portable electrochemical sensors combined with highly efficient glucose oxidation electrodes offers a significant opportunity for convenient glucose detection. In this report, we present the design and preparation of platinum deposited Ni/NiFe₂O₄/Carbon composite (Pt/Ni/NiFe₂O₄/C) derived from Ni/Fe metal–organic frameworks (MOFs) followed by Pt deposition. Energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and electron microscopy (EM) were utilized to analyze the crystal structure, morphology, and chemical composition of the resulting materials. The glucose sensing capabilities of the optimal Pt/Ni/NiFe₂O₄/C-3 were assessed using amperometry methods on a smartphone-based portable device. Acting as a nonenzymatic glucose sensor, the Pt/Ni/NiFe₂O₄/C-3 electrode demonstrated notable sensitivity and a low limit of detection for glucose. The portable sensor exhibits high sensitivities of 131.88 μM mM cm⁻² at low glucose concentration (3–500 μM) and 29.52 μA mM cm⁻² at high glucose concentration (700–4000 μM), achieving a low detection limit of 1.1 μM (S/N = 3). The sensor also demonstrates enhanced selectivity and stability for detecting glucose. Furthermore, the portable sensor exhibits a clear step-ampere response in the detection of serum samples with satisfactory recovery ranging from 99.30 to 101.32%. This suggests the significant potential of portable glucose sensing applications.

构建具有一维中空结构的 Pt/Ni/NiFe2O4/C 纳米复合材料，用于便携式葡萄糖传感应用。

设计与高效葡萄糖氧化电极相结合的便携式电化学传感器为实现便捷的葡萄糖检测提供了重要机遇。在本报告中，我们介绍了铂沉积镍/镍铁氧体/碳复合材料（Pt/Ni/NiFe2O4/C）的设计和制备，该材料源自镍/锗金属有机框架（MOFs），然后进行铂沉积。利用能量色散 X 射线光谱（EDS）、X 射线光电子能谱（XPS）、X 射线衍射（XRD）和电子显微镜（EM）分析了所得材料的晶体结构、形态和化学成分。利用基于智能手机的便携式设备上的安培计方法，对最佳 Pt/Ni/NiFe2O4/C-3 的葡萄糖传感能力进行了评估。作为一种非酶葡萄糖传感器，Pt/Ni/NiFe2O4/C-3 电极表现出显著的灵敏度和较低的葡萄糖检测限。该便携式传感器在葡萄糖浓度较低（3-500 μM）时的灵敏度高达 131.88 μM mM cm-2，在葡萄糖浓度较高（700-4000 μM）时的灵敏度高达 29.52 μA mM cm-2，检测限低至 1.1 μM（S/N = 3）。该传感器还具有更高的葡萄糖检测选择性和稳定性。此外，该便携式传感器在检测血清样品时表现出明显的阶跃安培响应，回收率在 99.30% 到 101.32% 之间，令人满意。这表明便携式葡萄糖传感应用潜力巨大。
