Non-Enzymatic Glucose Detection Based on NiS Nanoclusters@NiS Nanosphere in Human Serum and Urine

“…The Ni foam was washed successively with 10 min sonication in acetone and pure water. In typical, five continuous cyclic voltmmograms of the NF electrode in the cycling the potential window (+0.60 to −1.20 V (vs. Ag/AgCl)) in the electrolyte mixture of 5.0 mM Ni 2+ precursor + 0.75 M thiourea + 0.1 M HNO 3 at a scan rate of 5.0 mV s −1 [31]. The electrochemically deposited NC-NiS@NS-NiS nanomaterials with a mass loading of~0.026 mg were designated as NC-NiS@NS-NiS|NF.…”

“…The desirable electrodes for the design of the electrochemical glucose sensors may concomitantly have good electric conductivity and high electrocatalytic activity [30]. Among the various nanostructured transition metal-based materials, Ni-based nanomaterials have been broadly investigated due to their less expensive and satisfying electrocatalytic activity arisen from the Ni 2+ /Ni 3+ redox couple in an alkaline electrolyte [31][32][33]. Thus, the design of an enzyme-free high electrocatalytic active nanomaterials-based sensor platform for the sensitive and selective detection of glucose is required.…”

Gold-dispersed hierarchical flower-like copper oxide microelectrodes for the sensitive detection of glucose and lactic acid in human serum and urine

“…[11][12][13] Therefore, miniaturized electrochemical biosensor systems are extensively utilized in environmental detection, food industry, and clinical, biological and biomedical fields. [14][15][16][17][18][19] The sensing of glucose and lactic acid plays a vital role in clinical medicine, particularly in diabetes diagnosis. In recent years, the enzyme-free electrochemical detection of glucose and lactic acid has gained rigorous consideration with a great progress.…”

A facile chemical synthesis of nanoflake NiS2layers and their photocatalytic activity

“…30,31 However, the catalytic performance of NiS 2 in the degradation of organic pollutants such as endocrine disrupting compounds (EDCs) is still less competitive compared to other catalytic materials based on phosphides and noble metals. 4,13 In this regard, numerous techniques have been used to develop and fabricate nickel sulde nanostructures with good physical and chemical properties including hydrothermal methods, 23,32,33 solvothermal, 34 decomposition of single-source precursors, 35 microwave-assisted synthesis, 36,37 solventless route in air, 38 sonochemical, 39 and ultrasonic spray pyrolysis. 10 Most of these methods are suitable for preparing nickel suldes in powder form with other different phases sometimes accompanying.…”
