“…This peak may be attributed to the oxidation of Cu/Ni atoms during the electrochemical experiment in NaOH solution. The CV collected in the presence of 1 mM glucose concentration, resulted in signi cant oxidation current in the region of 0.5 -0.7 V. This is directly associated with the glucose oxidation reaction 12,24,36,37 . To uncover, if the observed performance is associated with the individual Cu or Ni atoms or whether the co-sputtered Cu-Ni thin lm exhibits a synergistic effect, we performed glucose-sensing experiments for Cu-and Ni-based electrodes under similar experimental conditions and collected CVs (Fig.…”

“…These results suggest that Cu-Ni co-sputtered thin lm exhibits synergistic activity toward glucose, therefore resulting in superior performance. When Cu and Ni work synergistically for glucose sensing, multiple electrochemical reactions occur simultaneously 37 . Initially, Cu and Ni atoms are oxidized and then participate in glucose oxidation reactions as expressed in reaction 1 and 2 37 .…”

In this work, we report a wafer-scale and chemical-free fabrication of nickel (Ni) and copper (Cu) heteroatomic Cu-Ni thin films using RF magnetron sputtering technique for non-enzymatic glucose sensing application. The as-prepared wafer-scale Cu-Ni thin films exhibits excellent electrocatalytic activity toward glucose oxidation with a 1.86 µM detection limit in the range of 0.01 mM to 20 mM range. The Cu-Ni film shows 1.3- and 5.4-times higher glucose oxidation activity in comparison to the Cu and Ni electrodes, respectively. The improved electrocatalytic activity is attributed to the synergistic effect of the bimetallic catalyst and high density of grain boundaries. The Cu-Ni electrodes also possessed excellent anti-interference characteristics. These results indicate that Cu-Ni heteroatomic thin film can be a potential candidate for the development of non-enzymatic glucose biosensor because of its chemical free synthesis, excellent reproducibility, reusability, and long-term stability.

“…Noticeably, most of these materials are prepared through self-assembly via a sol‒gel or hydrothermal route, which often involves supramolecular organization via molecular recognition between the specially designed species (e.g., between the oligomers and surfactants) [ 12 ]. Chemical vapor deposition and electrodeposition are also well-established approaches for making sophisticated nanostructures [ 13 , 14 ], but the sol‒gel and hydrothermal methods are more scalable for commercialization. Due to their special hierarchical nanostructures, dendritic metal oxides exhibit open macropores (>50 nm) and the large mesopores (2–50 nm).…”

In the past two decades, we have learned a great deal about self-assembly of dendritic metal oxide structures, partially inspired by the nanostructures mimicking the aesthetic hierarchical structures of ferns and corals. The self-assembly process involves either anisotropic polycondensation or molecular recognition mechanisms. The major driving force for research in this field is due to the wide variety of applications in addition to the unique structures and properties of these dendritic nanostructures. Our purpose of this minireview is twofold: (1) to showcase what we have learned so far about how the self-assembly process occurs; and (2) to encourage people to use this type of material for drug delivery, renewable energy conversion and storage, biomaterials, and electronic noses.

High fabrication cost, chemical instability, and complex immobilization of enzyme molecules are critical issues of enzyme‐based glucose sensors. Designing state‐of‐the‐art, binder‐free, and non‐enzymatic glucose sensing probes plays an imperative role to cope with the aforementioned issues. 3D carbonaceous nanomaterials coated with transition metal vanadates (TMVs) are a favorable biomimetic platform for glucose quantification. Peculiar hierarchical structure, enhanced conductivity, synergistic interaction, multiple oxidation states, and high catalytic activity would make such composite a potential contender for non‐enzymatic glucose sensing. Herein, 3D helical‐shaped carbon nanocoils (CNCs) are grown on nickel foam (NF) via chemical vapor deposition method to prepare a robust CNCs/NF scaffold. Then, a hydrothermal route is followed to grow interconnected free‐standing Ni3V2O8 nanosheets (NSs) on CNCs/NF scaffold. This novel and binder‐free Ni3V2O8 NSs/CNCs/NF hierarchical composite possesses superior electrochemical active area (ECSA) and exceptional electrochemical efficacy. Amperometric analysis exhibits extremely prompt detection time (0.1 s), elevated sensitivity (5214 µA mM−1 cm−2), and low detection limit (0.04 µM). Developed sensor demonstrates appreciable recoveries (93.3 to 103.3%) regarding glucose concentration in human serum. The appealing analytical results show that deployment of a 3D helical‐shaped hierarchical smart scaffold can be an effective strategy for developing efficient and advanced non‐enzymatic glucose sensors.
