“…The level of the glucose present in the blood sample was estimated from the linear fit of the plot (after subtracting the background glucose concentrations). 64 As shown in Table S1, the glucose concentration measured with Ni 3 Te 2 -based sensor, regardless of the fabrication method, was in good agreement with the results obtained from the commercial glucometer, confirming the possibility of Ni 3 Te 2 as a promising sensor for human blood glucose testing. Another growing emphasis for nonenzymatic glucose, especially with respect to the continuous glucose monitoring system, is to develop sensors that can detect very low amounts of glucose present in other bodily fluids such as sweat, urine, tears, tissue fluid, etc.…”

“…Glucose fuel cells are potential candidates to replace the lithium-ion batteries due to their superior long-term stability, sufficient power density, and abundance of glucose in the body to generate a continuous and stable power output. However, the main challenge for enzymatic glucose fuel cells is the poor anode selectivity toward glucose oxidation in the presence of oxygen in the body tissue. − Nonenzymatic glucose fuel cell with a high current response and excellent selectivity can be a feasible solution for improvements in power generation for implantable medical devices. It can be concluded from Figure b that electrodeposited Ni 3 Te 2 can be a potential choice for this technology, as it shows a high current density of about 45 mA cm –2 in the presence of 4 mM glucose.…”

Developing Nonenzymatic glucose biosensors has recently been at the center of attention owing to their potential application in implantable and continuous glucose monitoring systems. In this article, nickel telluride nanostructure with the generic formula of Ni 3 Te 2 has been reported as a highly efficient electrocatalyst for glucose oxidation, functional at a low operating potential. Ni 3 Te 2 nanostructures were prepared by two synthesis methods, direct electrodeposition on the electrode and hydrothermal method. The electrodeposited Ni 3 Te 2 exhibited a wide linear range of response corresponding to glucose oxidation exhibiting a high sensitivity of 41.615 mA cm –2 mM –1 and a low limit of detection (LOD) of 0.43 μM. The hydrothermally synthesized Ni 3 Te 2 , on the other hand, also exhibits an ultrahigh sensitivity of 35.213 mA cm –2 mM –1 and an LOD of 0.38 μM. The observation of high efficiency for glucose oxidation for both Ni 3 Te 2 electrodes irrespective of the synthesis method further confirms the enhanced intrinsic property of the material toward glucose oxidation. In addition to high sensitivity and low LOD, Ni 3 Te 2 electrocatalyst also has good selectivity and long-term stability in a 0.1 M KOH solution. Since it is operative at a low applied potential of 0.35 V vs Ag|AgCl, interference from other electrochemically active species is reduced, thus increasing the accuracy of this sensor.

“…As this system utilizes circulating glucose as in the human vein, it could be utilized as a power source within an implantable device. Su et al [ 65 ] also reported an interesting glucose-based NBFC, which included graphene sheets grafted with Pt and Pd as the anode and nitrogen-doped GO nanoribbons as the cathode. With physiological glucose (4 mM) in neutral cerebrospinal fluid, a high OCV of 0.216 V and maximal power output of 8.96 µW/cm 2 were obtained with great stability and durability, which maintained the initial power output during one week with only a 7.9% decrease.…”

The appearance and evolution of biofuel cells can be categorized into three groups: microbial biofuel cells (MBFCs), enzymatic biofuel cells (EBFCs), and enzyme-like nanomaterial (nanozyme)-based biofuel cells (NBFCs). MBFCs can produce electricity from waste; however, they have significantly low power output as well as difficulty in controlling electron transfer and microbial growth. EBFCs are more productive in generating electricity with the assistance of natural enzymes, but their vulnerability under diverse environmental conditions has critically hindered practical applications. In contrast, because of the intrinsic advantages of nanozymes, such as high stability and robustness even in harsh conditions, low synthesis cost through facile scale-up, and tunable catalytic activity, NBFCs have attracted attention, particularly for developing wearable and implantable devices to generate electricity from glucose in the physiological fluids of plants, animals, and humans. In this review, recent studies on NBFCs, including the synthetic strategies and catalytic activities of metal and metal oxide-based nanozymes, the mechanism of electricity generation from glucose, and representative studies are reviewed and discussed. Current challenges and prospects for the utilization of nanozymes in glucose biofuel cells are also discussed.

“…During the complete electrooxidation of a glucose molecule, glucose is oxidized to gluconic acid in alkaline medium, and the reaction steps are given as follows 11 :

Anodic reaction : C_{6} H_{12} O_{6} + 2 {OH}^{-} \to C_{6} H_{12} O_{7} + H_{2} normalO + 2 e^{-} .

Cathodic reaction : 0.5 O_{2} + H_{2} normalO + 2 e^{-} \to 2 {OH}^{-} .

Overall reaction : C_{6} H_{12} O_{6} + 0.5 O_{2} \to C_{6} H_{12} O_{7} .

More active catalysts are required to accelerate glucose electrooxidation reaction (GER) in direct liquid fuel cell. In recent years, metal and non‐metal catalysts like Ni‐Co composite, 12 Al‐Au‐ZnO, 13 N doped‐G‐ITO, 14 AuC, 15 Ag‐Ni foam, 16 PtPd/G, 17 Au‐Pani, 18 NiO x ‐MnO x ‐GC, 19 Au‐Ag/C, 20 MWCNT‐CoPc, 21 Au, 22 and benzothiophene derivatives 23 were employed to increase activity of GER. Additionally, Ji et al 24 developed porous Cu@Cu 2 O films supported with Pd nanoparticles for GER.…”

Herein, carbon nanotube (CNT) supported ruthenium (Ru), iridium (Ir), and copper (Cu) catalysts at 0.1 to 20 wt% metal loading are prepared by the NaBH4 reduction method for glucose electrooxidation reaction (GER). These catalysts are successfully characterized by X‐ray diffraction, scanning electron microscope, and N2 adsorption‐desorption measurements. Voltammetric measurements of these catalysts are taken using cyclic voltammetry and chronoamperometry techniques. The crystallite sizes of these catalysts are calculated as 2.53 nm for Ru/CNT, 2.94 nm for Ir/CNT, and 13.06 nm for Cu/CNT by using Scherrer equation. For GER, 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts have high current densities as 1.86 mA cm−2 (160.6 mA mg−1 Ru), 3.03 mA cm−2 (23 857.2 mA mg−1 Ir), and 1.12 mA cm−2 (1768.8 mA mg−1 Cu), respectively. These catalysts have also good stability. Results reveal that 10% Ru/CNT, 0.1% Ir/CNT, and 0.5% Cu/CNT catalysts are promising catalysts as direct glucose fuel cell anode catalysts.
