Electroanalytical detection of amlodipine in urine and pharmaceutical samples using Ag-Ce2(WO4)3@CNF nanocomposite-modified glassy carbon electrode

An amphiprotic paper-based electrode for glucose detection based on layered carbon nanotubes with silver and polystyrene particles

“…In the previous reports, 56,58,60,61,65 Ag-based electrodes showed excellent redox performance for different species. The oxidation reaction mechanisms of Ag nanoparticles in basic solution were attributed to the generation of the strong oxidant AgO(OH) 2 , 65 whereas their mechanisms for glucose redox in neutral 66–68 and acidic solutions were not clear. 69–71 For the current CNT-NH 2 –Ag/PS paper electrode, the redox reaction of glucose was performed in a neutral solution (Na 2 SO 4 system).…”

“…These results indicated that the redox reaction on the CNT-NH 2 -Ag/PS paper electrode was a diffusion-controlled electrochemical process. [62][63][64] whereas their mechanisms for glucose redox in neutral [66][67][68] and acidic solutions were not clear. [69][70][71] For the current CNT-NH 2 -Ag/PS paper electrode, the redox reaction of glucose was performed in a neutral solution (Na 2 SO 4 system).…”

Rapid quantitative detection of luteolin using an electrochemical sensor based on electrospinning of carbon nanofibers doped with single-walled carbon nanoangles

“…† The absorption peak at 1101 cm −1 corresponds to the C-N bond, and the stretching vibration of C]O was found at 1661 cm −1 . 29 In addition, the strong bands at 3434 cm −1 are attributed to the bending vibration of the -OH bond. 30…”
