Abstract

Constructing hybrid hollow nano-electrocatalysts with various transition metal sulfides (TMSs) is highly desirable for sensitive enzyme-free glucose monitoring, but limited research has been conducted due to the constraints of current demanding synthesis technologies. In this study, we integrated CuS and Co₃S₄ as hybrid nanocages (h-NCs) by advanced synthetic strategies, including coordinated etching and precipitation (CEP) and template ion reutilization. The resulting CuS/Co₃S₄ h-NCs induced good synergistic effect in electrocatalytic activities, glucose adsorption, and electrical conductivity, as validated by the density functional theory (DFT) calculations. When employed as glucose sensing platforms, electrodes incorporating CuS/Co₃S₄ h-NCs demonstrated high-performance sensing characteristics, with excellent sensitivities up to 2731.8 μA mM^-1 cm², wide linear range of 0.001-5.6 mM, low detection limit (90 nM), and ideal stability. Moreover, CuS/Co₃S₄ h-NCs were promising to analyze glucose in human serum with good recoveries ranging from 92.4 % to 96.7 %. These findings underscore the benefits of integrating different TMSs to create hybrid hollow nanomaterials, which optimize glucose sensing platforms and expand the design of high-performance electrocatalysts.

高灵敏度葡萄糖传感平台的离子再利用工程混合cu /Co3S4纳米笼。

用各种过渡金属硫化物（tms）构建杂化中空纳米电催化剂是实现无酶葡萄糖敏感监测的迫切需要，但由于目前合成技术的限制，研究很少。在这项研究中，我们采用先进的合成策略，包括协调蚀刻和沉淀（CEP）和模板离子回收，将cu和Co3S4集成为混合纳米笼（h-NCs）。得到的cu /Co3S4 h-NCs在电催化活性、葡萄糖吸附和电导率方面具有良好的协同效应，并通过密度泛函理论（DFT）计算得到了验证。采用cu /Co3S4 h-NCs电极作为葡萄糖传感平台，其灵敏度可达2731.8 μA mM-1 cm2，线性范围为0.001 ~ 5.6 mM，检出限低（90 nM），稳定性好。此外，cu /Co3S4 h-NCs有望分析人血清中的葡萄糖，回收率在92.4% ~ 96.7%之间。这些发现强调了整合不同的tms来创建混合中空纳米材料的好处，它可以优化葡萄糖传感平台并扩展高性能电催化剂的设计。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
