“…Specifically, the current density of 0.31 mA/cm −2 was obtained at the potential of 0.55 V. This indicates that the prepared Cu NP@PC is the best catalyst for glucose oxidation, which can be reasonable by its owning porous structure. As it is reported, the porosity can promote the mass transport [29]. Herein, to demonstrate the enhanced mass transport, the effect of scanning rates on the glucose oxidation was investigated on Cu NP@PC modified electrode.…”

“…The results showed a much wide linear range for the detection of glucose (from 0.001 to 14.00 mM), due to the nanoconfined effect from the porous carbon [28]. Using the metal-organic frameworks (MOFs) as self-sacrificial templates to prepare porous carbon materials, the nickel nanoparticles embedded on nanoporous carbon nanorods prepared by Jia et al presented good glucose sensing properties with the fast response times (within 1.6 s) [29]. Song et al constructed a composite (Cu@C-500) consisting of copper nanoparticle uniformly embedded porous carbon bed by using Cu MOF as a raw material.…”

An accurate sensor to rapidly determine the glucose concentration is of significant importance for the human body health, as diabetes has become a very high incidence around the world. In this work, copper nanoparticles accommodated in porous carbon substrates (Cu NP@PC), synthesized by calcinating the filter papers impregnated with copper ions at high temperature, were designed as the electrode active materials for electrochemical sensing of glucose. During the formation of porous carbon, the copper nanoparticles spontaneously accommodated into the formed voids and constituted the half-covered composites. For the electrochemical glucose oxidation, the prepared Cu NP@PC composites exhibit much superior catalytic activity with the current density of 0.31 mA/cm2 at the potential of 0.55 V in the presence of 0.2 mM glucose. Based on the high electrochemical oxidation activity, the present Cu NP@PC composites also exhibit a superior glucose sensing performance. The sensitivity is determined to be 84.5 μA /(mmol.L) with a linear range of 0.01 ~ 1.1 mM and a low detection limit (LOD) of 2.1 μmol/L. Compared to that of non-porous carbon supported copper nanoparticles (Cu NP/C), this can be reasonable by the improved mass transfer and strengthened synergistic effect between copper nanoparticles and porous carbon substrates.

Metal nanoclusters (NCs) protected by a thiolate ligand are fascinating for their unique geometrical structures and physicochemical properties. Herein, a ligand-based strategy to tailor the structures and electrocatalytic properties of self-assembled Cu NCs was proposed. By adjusting the molar ratio of two protected ligands (2,3,5,6-tetrafluorothiophenol and 2,3,4,5,6-pentafluorothiophenol), the morphology of assembled Cu NCs was changed from nanoribbons to ultrathin nanowires, nanonetworks, and then to nanosheets, which was similar to the weaving process of silk. When the fluorine substitution of thiophenol ligands increased from tetrasubstitution to pentasubstitution, the composition, geometrical structure, optical absorption spectrum, charge distribution, and electrostatic potential of Cu NCs changed and then affected the assembled architectures and the electrocatalytic activity of Cu NCs for glucose oxidation. On the basis of the excellent electrocatalytic performance of assembled Cu NCs, the as-prepared nanoribbons were successfully used for nonenzymatic electrochemical detection of glucose with a wider linear range located between 5 μM and 26 mM.

The development of a sensitive glucose monitoring system is highly important to protect human lives as high blood-glucose level-related diseases continue to rise globally. In this study, a glucose sensor based on polyaniline-bimetallic oxide (PANI-MnBaO2) was reported. PANI-MnBaO2 was electrochemically synthesized on the glassy carbon electrode (GCE) surface. The as-prepared PANI-MnBaO2 was characterized by field emission scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. Glucose sensing on PANI-MnBaO2 is based on the electrocatalytic oxidation of glucose to the glucolactone, which gives oxidation current. The oxidation potential for glucose was 0.83 V, with a limit of detection of 0.06 µM in the linear and in the concentration range of 0.05 µM–1.6 mM. The generated current densities displayed excellent stability in terms of repeatability and reproducibility with fast response. The development of a sensitive glucose sensor as obtained in the current study would ensure human health safety and protection through timely and accurate glucose detection and monitoring.
