Synthesis of nickel(ii) coordination polymers and conversion into porous NiO nanorods with excellent electrocatalytic performance for glucose detection

Abstract

Porous NiO nanostructures are fabricated by calcinating the Ni(SA)2(H2O)4coordination polymers and used as electrocatalysts for the detection of glucose in a nonenzymatic electrochemical sensor.

Alleviating concentration polarization: a micro three-electrode interdigitated glucose sensor based on nanoporous gold from a mild process

“…It can overcome the problem of enzyme inactivation and shows the advantages of good stability, low cost, simplicity and reproducibility. 4,[6][7][8][9] Different kinds of materials have been applied to construct nonenzymatic glucose sensors including metals, alloys, metal oxides, and carbon. [10][11][12][13][14][15] Among all kinds of materials, nanostructure metals are one of the most potential ones since they can supply more surface active sites and exhibit much higher catalytic performance.…”

Deposition of nanomaterials: A crucial step in biosensor fabrication

“…The oxidized CNTs had carboxylic moieties, which enhanced the enzyme loading and improved the sensing performance. Various other nanomaterials have been used for glucose sensor fabrication with a drop-casting method, such as CoWO4 nanospheres [88], carbon nanodots [89], nanostring cluster-structured Bi2O3 [90], nanoflower-like CoS-decorated 3D porous carbon skeletons [91], superhydrophobic mesoporous silicon nanowires (NWs) [9], cobalt phosphide (CoP) NRs [93], thin-walled graphitic nanocages [94], MnO2 NWs [95], Cu2O nanourchins [96], Ni(OH)2 nanoplates [97], Ni(OH)2-decorated sulfur-doped carbon NPs [98], and porous NiO nanorods (NRs) [99].…”

A yolk–albumen–shell structure of mixed Ni–Co oxide with an ultrathin carbon shell for high-sensitivity glucose sensors

“…[7][8][9] Among these transition metals, Co and Ni show superior electrocatalytic activity and high stability toward electro-oxidation of glucose in alkaline media. [10][11][12][13] In order to increase the electrocatalytic active surface area of these active materials, different kinds of nanostructures have been used for glucose electrocatalysis, such as nanowires, 13 nanosheets, 14 nanodisks, nanorods, 15 nanotubes, 16 nanoflowers 17 and so on. However, the poor electrical conductivity of these metal oxides and their tendency to aggregate has hindered their applications.…”
