Nanotechnology has opened new and exhilarating opportunities for exploring glucose biosensing applications of the newly prepared nanostructured materials. Nanostructured metal-oxides have been extensively explored to develop biosensors with high sensitivity, fast response times, and stability for the determination of glucose by electrochemical oxidation. This article concentrates mainly on the development of different nanostructured metal-oxide [such as ZnO, Cu(I)/(II) oxides, MnO2, TiO2, CeO2, SiO2, ZrO2, and other metal-oxides] based glucose biosensors. Additionally, we devote our attention to the operating principles (i.e., potentiometric, amperometric, impedimetric and conductometric) of these nanostructured metal-oxide based glucose sensors. Finally, this review concludes with a personal prospective and some challenges of these nanoscaled sensors.

A comprehensive review of glucose biosensors based on nanostructured metal-oxides.

Graphene quantum dots (GQDs) that are flat 0D nanomaterials have attracted increasing interest because of their exceptional chemicophysical properties and novel applications in energy conversion and storage, electro/photo/chemical catalysis, flexible devices, sensing, display, imaging, and theranostics. The significant advances in the recent years are summarized with comparative and balanced discussion. The differences between GQDs and other nanomaterials, including their nanocarbon cousins, are emphasized, and the unique advantages of GQDs for specific applications are highlighted. The current challenges and outlook of this growing field are also discussed.

Recent Advances on Graphene Quantum Dots: From Chemistry and Physics to Applications

The [CoL(PR3)(CH3OH)]ClO4 (where L = MeSalophen, 5-NO2MeSalophen, 5-BrMeSalophen, 5-MeOMeSalophen, 4-MeOMeSalophen, 3-MeOMeSalophen and R=Ph or Bu) complexes were synthesized and also characterized by FTIR, UV–Vis, 1H NMR and 13C NMR spectroscopies. The absorptions between 550 and 750 nm for the complexes are attributed to d–d transitions. Electrochemical properties of the complexes were examined by means of cyclic voltammetry. The anodic peak potentials were more positive in the following trend NO2 > Br > H > MeO and are in accordance with electronic effects of the substituents. The crystal structure of [Co(5-NO2MeSalophen)(PBu3)(CH3OH)]ClO4 and [Co(5-BrMeSalophen)(PPh3)(CH3OH)]ClO4 was determined by single-crystal X-ray diffraction. They showed six-coordinated pseudo-octahedral geometries in which equatorial planes are formed by the O(1), O(2), N(1) and N(2) atoms of the Schiff base and the axial positions were occupied by PR3 and methanol.

Sensitive quantification of trace zinc in water samples by adsorptive stripping voltammetry

The present study aimed to report a novel electrochemical sensor through electropolymerization of o-aminophenol (o-AP) and m-dihydroxy benzene (m-DB) as monomers on the surface of the glassy carbon electrode (GCE) for the determination of histidine (His) as a template molecule. The developed sensor exhibited satisfactory sensitivity and high selectivity, and also offered a linear range between 0.005 and 10.0 μM with a detection limit of 0.9 nM. Finally, it is worth mentioning that we also aimed at employing the proposed sensor for the detection of His in blood serum samples.

A novel electrochemical sensor for the determination of histidine based on a molecularly imprinted copolymer

The fabrication of hierarchical nanostructure based on metal–organic frameworks (MOFs)-derived transition-metal phosphides (TMPs) has become a hot topic in electrochemical sensor application owing to its unique properties. Herein, a scalable and facile strategy was proposed to prepare MOF-derived bimetallic Zn-Ni-P nanostructures. The material characterization showed that MOFs-derived Zn-Ni-P has flower-like structure that built from small 2D nanosheets. The MOFs-derived Zn-Ni-P was prepared via a facile phosphorization of Zn-Ni-MOF precursor in N2 atmosphere. This MOF-derived TMPs electrode materials offer excellent electrocatalytic activity toward isoprenaline (IPN) oxidation. In addition, the electrode shows wide two linear range (0.2 µM −5 mM and 5 mM-14 mM), short response time (<1s), low detection limit (0.06 µM), good sensitivity (66.748 μA mM−1), desirable repeatability and reproducibility (RSD < 3.5%), and capability for measuring IPN in real sample, which are comparable or better than most reported works for measuring IPN. This improvement can be due to the synergistic effects of multiple catalytic centers, high surface area, facilitated mass, and electron transfer.
