“…It is worth mentioning that despite higher detection limits, non-enzymatic glucose biosensors based on metal oxides are currently the most studied. In the last three years, nonenzymatic glucose sensor based on metal-oxides nanomaterials were also designed by Awais and co-authors (2021), Babulal and co-authors (2021), Lotfi and co-authors (2021), Yang and co-authors (2021), Yin and co-authors (2021), Espro and co-authors (2020), Wei and co-authors (2020), Jo and co-authors (2020), Inyang and co-authors (2020), Lin and co-authors (2019) and many others (25)(26)(27)(28)(29)(30)(31)(32)(33)(34).…”

AIMS: This review article focuses on electrochemical biosensors in the diagnosis of diabetes mellitus and their latest trends and advances. In particular, non-enzymatic, non-invasive, wearable, and non-glucose biosensors are described. METHODS: The current literature was searched and recent works on this matter were cited and discussed in the text of this paper. RESULTS: The overworld health problem, the incurable disease, the global burden on health insurers and society, and above all one of the leading causes of death -all characterize diabetes mellitus, a lifelong chronic disease that affects hundreds of millions of people around the world. The new types of biosensors bring new opportunities in the care of diabetic patients and improve current methods. The practical relevance of the recent fi ndings is expected in medicine in next years. CONCLUSIONS: The authors summarized the modern possibilities of biosensing, their pros and cons, and their perspectives for the future. The discussion outcome from the current literature (Tab. 4, Fig. 1, Ref. 63).

“…[11][12][13] In most studies of non-enzymatic glucose sensors using Co 3 O 4 as a catalyst, the Co 3 O 4 precursor is annealed at a temperature of 300 °C or higher for several hours for the sintering of cobalt oxide nanoparticles. [14][15][16][17][18][19][20] In this study we propose a synthesis method that uses a laser to shorten the existing Co 3 O 4 synthesis process, which requires several hours under high-temperature conditions, to less than 1 ms without high-temperature conditions using a laser. The PI film and the spin-coated Co-hydrogel absorb the IR energy of the laser and generate a temperature of over 2000 K locally for less than 1 ms. [21] In this process, the residual solvent in the PI film and Co-hydrogel is explosively evaporated to form nanofiber-type graphene with cobalt oxide particles attached to it.…”

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.

“…Besides this, the extremely low level of DA (<1 µM) compared to the concentration of AA (100-1,000 times higher than that of DA) needs to be considered (Ghanbari and Hajheidari, 2015;Edris et al, 2018). To address these issues, as well as the slow interfacial electron transfer, chemically modified electrodes (Anu Prathap et al, 2019) have been developed as sensing platforms based on conductive polymers (Xie et al, 2017;Li et al, 2019), MOFs (Fang et al, 2018), carbonaceous nanomaterials (Luo et al, 2016;Abellán-Llobregat et al, 2018), metal/metal oxide nanoparticles (Chen et al, 2018;Zhao et al, 2019a), and their composites (Grace et al, 2019;Lin et al, 2019;Zhao et al, 2019b).…”

A metal-organic gel (MOG) similar in constitution to MIL-100 (Fe) but containing a lower connectivity ligand (5-aminoisophthalate) was integrated with an isophthalate functionalized graphene (IG). The IG acted as a structure-directing templating agent, which also induced conductivity of the material. The MOG@IG was pyrolyzed at 600 • C to obtain MGH-600, a hybrid of Fe/Fe 3 C/FeO x enveloped by graphene. MGH-600 shows a hierarchical pore structure, with micropores of 1.1 nm and a mesopore distribution between 2 and 6 nm, and Brunauer-Emmett-Teller surface area amounts to 216 m 2 /g. Furthermore, the MGH-600 composite displays magnetic properties, with bulk saturation magnetization value of 130 emu/g at room temperature. The material coated on glassy carbon electrode can distinguish between molecules with the same oxidation potential, such as dopamine in presence of ascorbic acid and revealed a satisfactory limit of detection and limit of quantification (4.39 × 10 −7 and 1.33 × 10 −6 M, respectively) for the neurotransmitter dopamine.
