Improvement of sensitive Ni(OH)2 nonenzymatic glucose sensor based on carbon nanotube/polyimide membrane

Synthesis and characterization of α-nickel (II) hydroxide particles on organic-inorganic matrix and its application in a sensitive electrochemical sensor for vitamin D determination

“…The Ni(OH) 2 can be obtained by electrochemistry process [9] and by chemical reactions using nickel salts [10], which are widely used in the development of electrochemical sensors [11,12]. Vitamin D 3 , also known as cholecalciferol, is one of the forms of vitamin D and can be obtained by endogenous (exposure to sunlight) and exogenous (through food) mechanisms.…”

Application of Semipermeable Membranes in Glucose Biosensing

“…It was observed that polypyrrole film porosity improved the surface area showing higher activity towards glucose oxidation compared to bi-metal electrodes without the conductive polymer film. Jiang et al reported on the fabrication of a glucose biosensor utilizing electrochemical deposition of Ni(OH) 2 onto carbon nanotube/polyimide (PI/CNT) membrane [41]. The fabricated sensor exhibited a sensitivity of 2.071 mA/mM·cm 2 along with a detection limit of 0.36 µM at SNR of 3.…”

“…The fabricated sensor exhibited a sensitivity of 2.071 mA/mM·cm 2 along with a detection limit of 0.36 µM at SNR of 3. The electrodeposition of Ni(OH) 2 onto carbon nanotube/polyimide (PI/CNT) membrane exhibited long-term stability and good reproducibility when operating in human serum and clearly resulted in an improvement in sensitivity compared to the chitosan membrane employed [41]. Conductive polymers, such as polyaniline (PANI) are also being employed as semipermeable membranes to screen against the interfering species such as uric acid, ascorbic acid and acetaminophen.…”

Non-enzymatic glucose sensor based on Au nanoparticles decorated ternary Ni-Al layered double hydroxide/single-walled carbon nanotubes/graphene nanocomposite

“…Au, Pt) [7,8], transition metal oxides (e.g. CuO, NiO, MnO 2 ) [9][10][11][12][13][14], transition metal hydroxides [15,16] and metal complexes [17] incorporated into appropriate matrices, taking the advantages of simplicity, reproducibility and stability in aggressive environment. Among them, gold nanoparticles (NPs) especially show fascinating properties for the oxidation of glucose, such as stable chemical property, favorable biocompatibility, good conductivity, high catalytic activity and good anti-poisoning property [18][19][20][21][22][23].…”
