Nonenzymatic glucose sensor based on nickel(II)oxide/ordered mesoporous carbon modified glassy carbon electrode

Facile synthesis of ultrafine Co3O4 nanocrystals embedded carbon matrices with specific skeletal structures as efficient non-enzymatic glucose sensors

“…The disease, which results from insulin deficiency, is one of the leading causes of death and disability [1]. Millions of diabetic in sensing application due to their outstanding properties such as low cost, excellent semi-conductivity, and good biocompatibility [12][13][14][15][16][17][18]. Among various kinds of transition metal oxides, Co 3 O 4 shows intriguing electronic, electrochemical, and electro-catalytic properties.…”

Synthesis of reduced graphene oxide intercalated ZnO quantum dots nanoballs for selective biosensing detection

“…[17] Among them, ZnO as a functional semiconductor with wide band gap and controllable electrical conductivity has attracted much attention in the field of sensing. [18,19] Many researches have demonstrated that ZnO nanostructure was a good candidate for sensing applications. In the aggregation of ZnO QDs, electrons trapped at the defect build up an electrostatic potential barrier known as Schottky barrier in the crystal grain boundary.…”

Three-Dimensional Porous NiO Nanosheets Vertically Grown on Graphite Disks for Enhanced Performance Non-enzymatic Glucose Sensor

“…Among these materials, NiO has been the focus of research. Obviously, the mechanism of a nonenzymatic glucose sensor is based on direct oxidation of glucose to glucolactone by high valence metal ions on the electrode surface [1,22,30]. Therefore, more exposed electrocatalytic active sites of the active material on the electrode surface should deserve great attention for design of sensors with enhanced performance.…”
