“…S5). This value is similar to that of the pillar-like-structured Cu film [38] and more negative than that of 0.65 V [38,39] or 0.55 V [40] at Cubased electrodes, respectively. These results suggest a preferable catalytic activity towards glucose at the Cu MD electrode.…”

“…S5). After an injection of some glucose into a blank solution, the catalytic current reached 90% of the maximum, which was below 3 s. This value is similar to that of the pillar-like-structured Cu film [38] and smaller than that of the Cu nanocubes on the multi-walled carbon nanotube arrays with a value of 5 s [41]. Moreover, the detection limit is 1.4 μM (S/N=3), smaller than that of the Cu nanobelt and Cu-CuO nanowire-modified electrodes with a value of 10 μM [42] and 0.05 mM [43], respectively.…”

Ultra-long Cu microdendrites (MDs) were prepared by one-step electrodeposition on a glassy carbon electrode. The results demonstrated that the reduction potential, pH, and temperature of the electrolysis solution, as well as the amount of Cu 2+ and citrate ions, play important roles in the formation of the Cu MDs. Notably, the X-ray diffraction experiments confirmed that the aggregations of the Cu nanocrystals preferred to grow along (111) direction. In addition, the resulting Cu MDs-modified electrode showed good electrochemical performance as a non-enzyme glucose sensor in alkaline media.

Metallic Bi and Ni were co‐deposited onto the surface of glass carbon electrode (GCE) from the electrolyte solution containing their respective nitrate to fabricate a Bi/Ni alloy modified GCE (Bi/Ni‐GCE). The purpose is to study the influence of Bi3+ on the deposition of Ni and that of deposited Bi on the electrocatalytic performance of Ni to glucose in alkali solution. The results show that both redox signal of Ni(OH)2/NiOOH and Ni(OH)2/NiOOH mediated electrocatalysis to glucose is remarkably increased in the presence of Bi. It seems that there is a synergistic effect between Bi and Ni on each other’s redox electrochemistry. It’s possible that the firstly deposited Bi on GCE surface helps to the following nucleation and growth of Ni, leading to the deposition of more metallic Ni on GCE surface. An extremely attractive feature of Bi/Ni‐GCE is reflected by the fast response time to the electrocatalytic oxidation of glucose. The electrode nearly responses immediately after glucose is added and it reaches a steady‐state level within only 2 seconds, demonstrating a good electrocatalytic property of Bi/Ni‐GCE. The calibration plot is linear over the wide concentration range of 0–5.8 mM with a sensitivity of 33.96 µA/mM and a correlation coefficient of 0.9985. The detection limit of the glucose was found to be 0.59 µM at a signal‐to‐noise ratio of 3. The fabricated Bi/Ni‐GCE was successfully employed to analyze the glucose level in blood samples, exhibiting high accuracy, strong resistance against inference and good reliability in the practical applications.

We describe a new electrochemical platform for direct sensing of glucose. The electrode was prepared by controlled electrodeposition of nickel nanoparticles onto carbon nanotubes on a copper electrode. The sensor was optimized by investigating the effects of the concentration of nickel precursor, electrolysis time and acidity of the medium. The nanocomposite was characterized by scanning electron microscopy and energy dispersive spectroscopy. Cyclic voltammetry of glucose in 0.1 M NaOH solution gives a well-defined anodic wave with a peak potential at 0.53 V (vs. Ag/AgCl) that indicates the direct electrooxidation of glucose at the nanomaterial. The electrode responds to glucose over a wide linear range (from 2 μM to 10 mM), with high sensitivity (3.8 mA mM −1 cm −2 ) and a low detection limit (0.7 μM). The sensor was applied to the determination of glucose in blood samples, and the results were in good agreement with data obtained by a commercially available glucometer. The method holds promise due to the ease of sensor fabrication and its robust performance and longevity.
