“…The current‐glucose concentration plot (Figure 6c) is explained through the Langmuir isothermal theory [34,35] . The glucose concentration on the electrode surface ( C G‐S ) follows Equations (5) and :

true C_{normalG - normalS} = \frac{K_{A} C_{G} C_{normalt normalm}}{1 + K_{A} C_{G}}

true I \propto C_{normalG - normalS} = K_{R} C_{normalG - normalS} = \frac{K_{R} K_{A} C_{G} C_{normalt normalm}}{1 + K_{A} C_{G}} = \frac{normalK C_{G}}{1 + K_{A} C_{G}}

“…The decrease in sensitivity at high glucose concentrations is because the diffusion rate of glucose in the electrolyte containing high concentrations of glucose exceeds the rate of consumption at the electrode interface, and the rate of charge flow limits the electrochemical reaction rate. In addition, the sensitivity of the electrode decreases because the reactive intermediate is adsorbed to the active region and the active region that oxidizes glucose decreases [35] . The relative standard deviation (RSD) values at each concentration were different, and the maximum value was 7.72 % at 1 μ m , and the minimum value was 0.03 % at 2 m m .…”

In this study, an electrochemical non‐enzymatic glucose sensor based on cobalt oxide was designed through CO2 laser irradiation on a Co‐hydrogel formed by spin‐coating a mixture of CoCl2 and gelatin on a polyimide (PI) film. The PI film, which absorbed IR energy through laser irradiation, was grown into laser‐induced graphene fiber (LIGF) with high electrical conductivity and a large surface area. The Co‐hydrogel absorbed the laser‘s IR energy and grew into laser‐induced Co3O4 nano particles (LICONPs) without high temperature annealing for several hours. Because the Co‐hydrogel and the PI film were simultaneously irradiated with laser, LICONPs were attached to the surface of the LIGF, so it had an active surface area 10.5 times larger than the geometric area. The fabricated LICONPs/LIGF was then utilized as a non‐enzymatic glucose sensor working electrode, resulting in high sensitivity of 187,129 μA mM−1 cm−2 in the range of 1–30 μm and low limit of detection (LOD) of 0.10 μm. In addition, LICONPs/LIGF also showed stable reproducibility, repeatability and long‐term stability when used as a part of working electrode of a non‐enzymatic glucose sensor.

Diabetes is a health disorder that necessitates constant blood glucose monitoring. The industry is always interested in creating novel glucose sensor devices because of the great demand for low-cost, quick, and precise means of monitoring blood glucose levels. Electrochemical glucose sensors, among others, have been developed and are now frequently used in clinical research. Nonetheless, despite the substantial obstacles, these electrochemical glucose sensors face numerous challenges. Because of their excellent stability, vast surface area, and low cost, various types of 2D materials have been employed to produce enzymatic and nonenzymatic glucose sensing applications. This review article looks at both enzymatic and nonenzymatic glucose sensors made from 2D materials. On the other hand, we concentrated on discussing the complexities of many significant papers addressing the construction of sensors and the usage of prepared sensors so that readers might grasp the concepts underlying such devices and related detection strategies. We also discuss several tuning approaches for improving electrochemical glucose sensor performance, as well as current breakthroughs and future plans in wearable and flexible electrochemical glucose sensors based on 2D materials as well as photoelectrochemical sensors.

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.
