“…The nanorod diameter was 28–80 nm and the length was 0.4–1.2 µm (Figure ). The obtained β‐AgVO 3 nanorods were smaller than the AgVO 3 nanobelts, which indicated that the catalytic activity of β‐AgVO 3 nanorods should be higher than that of the AgVO 3 nanobelts. The as‐prepared sample was investigated using ICP‐MS (Table ).…”

“…Such materials include metallic oxide nanoparticles (CeO 2 , Co 3 O 4 , V 2 O 5 , CuO, and MnO 2 ,), metallic and bimetallic nanostructures (Au, Ag, Pt, AFt‐Fe‐Pt,and Au@PtAg), carbon‐based nanomaterials (graphene oxide, carbon nanotubes, carbon dots), and bimetallic oxide nanoparticles (ZnFe 2 O 4 , CoFe 2 O 4 , FeWO 4 , and NiFe 2 O 4 ), which have been applied in colorimetric sensing based on their peroxides‐like activity. Among them, the bimetallic oxide alum was not included until Zhang et al . reported that AgVO 3 nanobelts exhibited intrinsic peroxidase‐like activity.…”

β‐AgVO3 nanorods have been demonstrated to exhibit intrinsic peroxidase‐like activity. The oxidation of glucose can be catalyzed by glucose oxidase (GOx) to generate H2O2 in the presence of O2. The β‐AgVO3 nanorods can catalytically oxidize peroxidase substrates including o‐phenylenediamine (OPD), 3,3′,5,5′‐tetramethylbenzidine (TMB), and diammonium 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonate) (ABTS) by H2O2 to produce typical color reactions: OPD from colorless to orange, TMB from colorless to blue, and ABTS from colorless to green. The catalyzed reaction by the β‐AgVO3 nanorods was found to follow the characteristic Michaelis–Menten kinetics. Compared with horseradish peroxidase and AgVO3 nanobelts, β‐AgVO3 nanorods showed a higher affinity for TMB with a lower Michaelis–Menten constant (Km) value (0.04118 mM) at the optimal condition. Taking advantage of their high catalytic activity, the as‐synthesized β‐AgVO3 nanorods were utilized to develop a colorimetric sensor for the determination of glucose. The linear range for glucose was 1.25–60 μM with the lower detection limit of 0.5 μM. The simple and sensitive GOx‐β–AgVO3 nanorods–TMB sensing system shows great promise for applications in the pharmaceutical, clinical, and biosensor detection of glucose.

“…To date, a large number of nanomaterials have been found to possess unexpected peroxidase-like activity (mimicking the functions of peroxidase), including Pt nanoclusters [ 15 ], AgVO 3 nanobelts [ 16 ], MnO 2 nanoparticles (NPs) [ 17 , 18 , 19 ], WO x quantum dots [ 20 ], Ag NPs [ 21 ], V 2 O 5 nanowires [ 22 ], and Fe 3 O 4 magnetic nanoparticles (MNPs) [ 23 , 24 , 25 ].

Porous CoFe2O4 was prepared via a simple and controllable method to develop a low-cost, high-efficiency, and good-stability nanozyme. The morphology and microstructure of the obtained CoFe2O4 was investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), specific surface area and pore analysis, and Raman spectroscopy. The results show that the annealing temperature has an important effect on the crystallinity, grain size, and specific surface area of CoFe2O4. CoFe2O4 obtained at 300 °C (CF300) exhibits the largest surface area (up to 204.1 m2 g−1) and the smallest grain size. The peroxidase-like activity of CoFe2O4 was further verified based on the oxidation of peroxidase substrate 3,3’,5,5’-tetramethylbenzidine (TMB) in the presence of H2O2. The best peroxidase-like activity for CF300 should be ascribed to its largest surface area and smallest grain size. On this basis, an effective method of colorimetric detection H2O2 was established. In addition, the porous CoFe2O4 was also used for the catalytic oxidation of methylene blue (MB), indicating potential applications in pollutant removal and water treatment.

“…Vanadium has found innumerous applications in medicine, particularly because this element can mimic both enzymes for antioxidant activity and insulin . Xiang et al.demonstrated that AgVO 3 nanobelts (100 nm width and 0.5‐5 μm length) presented peroxidase‐like activity and could be used as a probe for quantitative determination of H 2 O 2 (range from 0.075 to 0.5 mM) . In terms of biomedical engineering, Bock et al.underlined the application of silver vanadium oxides for batteries in implantable cardiac defibrillators (ICD).…”

Silver vanadates have been widely investigated because of their many interesting properties and their potential use in several applications. In addition to this, a large number of groups have investigated silver vanadates in the form of nanostructures. Here, we address first the synthesis and properties of nanosilver vanadate. Different techniques, such as precipitation, thermal decomposition, hydrothermal treatment, and sol-gel, are among the methods that have been employed for the controlled synthesis of silver vanadate. The use of nanosilver vanadate for the development of novel electronic devices, catalysts, and antibacterial agents for industry and biomedical applications will then be discussed. In this sense, the present review highlights the major advances regarding the synthesis, properties and applications of nanostructured silver vanadates.
