“…As the calcination temperature increasing from 550 °C to 750 °C, the particles further fused, agglomerated, and large irregular lump morphology could be observed at 750 °C, as shown in Figure 2(C)–Figure 2(E). This phenomena could also be founded in reported literature [25] . The TEM measurement further confirmed the successful preparation of Fe/Fe 3 O 4 @C‐ 650 .…”

In this paper, a novel composite of Fe/Fe 3 O 4 @C is synthesized by taking a Fe-metal-organic framework (Fe-MOF) as precursor template. Different treating temperature (450, 550, 650 and 750 °C) were carried out to investigate the composite of calcined products. The Fe/Fe 3 O 4 @C -650 modified glassy carbon electrode (Fe/Fe 3 O 4 @C -650 GCE) shows good electrocatalytic activity towards dopamine (DA) oxidation. Three electrochemical measuring methods of cyclic voltammetry (CV), differential pulse voltammetry (DPV) and amperometry i-t are adopted to investigate the sensing behaviors of Fe/Fe 3 O 4 @C -650 /GCE. The results show that: the sensors based on CV and DPV technology exhibit excellent advantages in the aspect of sensitivity and linear range thanthose of the sensor based on amperometry i-t technology. Meanwhile, the sensor based on CV method shows good selectivity for dopamine, and can resist the influence of various sugars, uric acid, ascorbic acid, as well as Na + and K + . The sensor also shows good stability and repeatability in the sensing process. In addition, the Fe/Fe 3 O 4 @C -650 /GCE could be successfully applied in the DA detection in the human serum.

“…Because cobalt contained in LICONPs acts as a catalyst for glucose oxidation, Nafion/LICONPs/LIGF increased the current in the glucose‐containing electrolyte.

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.

“…[4][5][6] Naturally, people look for alternative yet attractive strategy like deploying non-enzymatic glucose sensors due to their lower cost, easy processing and storage, faster response, and long lifespan. It was revealed that various metals in their oxide forms exhibit good electrocatalytic behaviour and could oxidize glucose directly e.g., cobalt, 7 nickel, 8,9 palladium, 10 vanadium, 11 copper, 12 molybdenum 13 etc. Their glucose oxidizing capability makes them potential candidates for selective and accurate detection of glucose present in the solution, or serum in very low concentration.…”

The present work demonstrates fabrication of a non-enzymatic glucose sensor based on CuO nanoparticles deposited over poly(3,4-ethylenedioxythiophene) (PEDOT) conducting polymer infiltrated with MoS2. Structural, morphological and elemental analysis of the fabricated sensor electrodes were performed via different characterization techniques like x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), elemental dispersive x-ray spectroscopy (EDX), and Fourier transform infra-red spectroscopy (FTIR). The cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) studies of the hybrid nanoelectrode (CuO/PEDOT-MoS2) exhibited better redox activity and electron transfer kinetics, as compared with the CuO/PEDOT and CuO only systems. Moreover, the electrochemical parameters of all the systems were determined and compared accordingly while CuO/PEDOT-MoS2 hybrid system offers a significant enhancement in the electroactive area (~1.47 cm- 2) and rate constant (0.76 s-1) towards oxidizing glucose into gluconic acid. In the CV responses, an augmented activity was monitored at +0.6 V which was considered as the dc bias potential in the chronoamperometric experiment for detecting glucose. The sensor electrode yielded a low LOD of 0.046 μM and with a sensitivity magnitude as high as 829 µA mM-1 cm-2 over a wide linear range, between 30 μM to 1.06 mM of glucose concentration.
