In this work, NiCo2S4 nanosheet-decorated Cu7S4 hollow microcubes were synthesized by electroless deposition and hydrothermal techniques for electrochemical determination of glucose in human serum. First, Cu2O cubes were synthesized at room temperature by electroless deposition, while the NiCo precursors (NiCo2O4 nanosheets) were grown using the hydrothermal process. Afterward, a Cu7S4–NiCo2S4 composite was synthesized via one-step vulcanization of Cu2O and NiCo2O4 using Na2S. The crystal structure, elemental valence state, and morphology of the synthesized Cu7S4–NiCo2S4 composite were investigated using X-ray diffraction, X-ray photoelectron energy spectroscopy, scanning electron microscopy, and transmission electron microscopy. Note that the hollow-structured Cu7S4 can not only serve as the substrate for NiCo2S4 nanosheets to enhance the specific surface area but also promote the electron transfer and improve the electrocatalytic activity of the Cu7S4–NiCo2S4 composite. By optimizing the experimental parameters of the applied potential, the amount of Cu7S4–NiCo2S4 composite, and the concentration of NaOH solution, the Cu7S4–NiCo2S4-modified glassy carbon electrode demonstrates a good linear relationship with glucose concentrations in the ranges of 0.002–0.3 and 0.3–20 mM, with sensitivities of 430 and 162 μA mM–1 cm–2, respectively. The detection limit is 0.4 μM (S/N = 3). The proposed sensor exhibits remarkable performance in detecting the glucose content in human serum, implying its immense practical potential.

Background Efficient monitoring of glucose concentration in the human body necessitates the utilization of electrochemically active sensing materials in nonenzymatic glucose sensors. However, prevailing limitations such as intricate fabrication processes, lower sensitivity, and instability impede their practical application. Herein, ternary Cu-Co-Ni-S sulfides nanoporous network structure was synthesized on carbon fiber paper (CP) by an ultrafast, facile, and controllable technique through on-step cyclic voltammetry, serving as a superior self-supporting catalytic electrode for the high-performance glucose sensor. Results The direct growth of free-standing Cu-Co-Ni-S on the interconnected three-dimensional (3D) network of CP boosted the active site of the composites, improved ion diffusion kinetics, and significantly promoted the electron transfer rate. The multiple oxidation states and synergistic effects among Co, Ni, Cu, and S further promoted glucose electrooxidation. The well-architected Cu-Co-Ni-S/CP presented exceptional electrocatalytic properties for glucose with satisfied linearity of a broad range from 0.3 to 16,000 μM and high sensitivity of 6829 μA mM− 1 cm− 2. Furthermore, the novel sensor demonstrated excellent selectivity and storage stability, which could successfully evaluate the glucose levels in human serum. Notably, the novel Cu-Co-Ni-S/CP showed favorable biocompatibility, proving its potential for in vivo glucose monitoring. Conclusion The proposed 3D hierarchical morphology self-supported electrode sensor, which demonstrates appealing analysis behavior for glucose electrooxidation, holds great promise for the next generation of high-performance glucose sensors.
