Fabrication of nano-copper/carbon nanotubes/chitosan film by one-step electrodeposition and its sensitive determination of nitrite

Nitrite ion-induced fluorescence quenching of luminescent BSA-Au25nanoclusters: mechanism and application

“…59,60 This LOD was comparable with or better than those obtained using other nanomaterial-based sensors for nitrite. [61][62][63][64][65][66] The good sensitivity and wide linearity for the detection of nitrite suggests great potential of BSA-Au NCs/7 th d for application in bioassays.…”

Electrocatalytic oxidation of acetylsalicylic acid at multiwalled carbon nanotube-alumina-coated silica nanocomposite modified glassy carbon electrodes

“…CNT-based electrodes have been increasingly used to solve demanding electrochemical problems and often they offer advantages over other types of electrode materials. The electrocatalytic ability of CNTs to enhance electron transfer of different electrochemical reactions such as ␤-nicotinamide adenine dinucleotide (NADH) [26], horseradish peroxidase [27], nitrite [28], methanol [29], and carbon monoxide [30] has been reported in the literature. This behavior can be attributed to the presence of edge-plane like sites located at the end and in the defect areas of the CNTs [31].…”

Electrochemical Determination of Nitrite and Iodate Based on Pt Nanoparticles Self-assembled on a Chitosan Modified Glassy Carbon Electrode

“…This porous structure can be useful to adsorb particles and analytes onto the electrode surface to fabricate all kinds of sensors. [24][25][26][27][28][29][30] The electrochemical properties of the modified electrodes were investigated by CV. As shown in Fig.…”

“…11,12 Many studies have reported on the ability of chitosan to bind with metal ions and the support metal nanoparticles, [13][14][15][16][17][18][19][20][21][22][23] and several electrochemical sensors have been developed based on the interaction between chitosan and analytes. [24][25][26][27][28][29][30] However, we have not found any papers concerning the detection of iodate using a chitosan-modified electrode. In the present work, we investigated the synthesis of Pt nanoparticles (nano-Pts) by a simple method, and then self-assembled on the chitosan modified glassy carbon electrode.…”
