[ 1 ] - Synergistic Effect of ZnO Nanoparticles and Carbon Nanotube and Polymeric Film on Electrochemical Oxidation of Acyclovir

A simple and selective carbon paste electrode has been developed for the electrochemicaldetermination of acyclovir (ACV). This electrode was designed by incorporation of multiwalledcarbon nanotubes (MWCNTs) and ZnO nanoparticles into the carbon paste matrix,and then poly (o-aminophenol; OAP) film were subsequently electropolymerized on it. Thesurface structure of nanoparticles were characterize...

[ 2 ] - Kinetic Study of the Electrocatalytic Oxidation of Acetaldehyde at Ni/Al Layered Double Hydroxide Modified sol-gel derived carbon ceramic electrode

In this research, we reported a novel modified carbon ceramic electrode (CCE) using Ni/Al Layered double hydroxide as modifier was fabricated by sol-gel technique. The Ni/Al Layered double hydroxide modified sol gel derived carbon ceramic (Ni/Al LDH-SGD-CC) electrode was used for electrocatalytic oxidation of acetaldehyde. The oxidation of acetaldehyde happens at the potential where Ni (III) sp...

[ 4 ] - Synergetic signal amplification of multi-walled carbon nanotubes-Cetyltrimethylammonium Bromide and Poly-L-Arginine as a highly sensitive detection platform for Rutin

In this research, a glassy carbon electrode was coated with a thin layer of multi-walled carbon nanotubes in the presence of the surfactant and subsequently was electro-polymerized with Poly-L-arginine (P-L-Arg). The prepared electrode was used as an effective sensor for the quantitative detection of Rutin (Ru). The fabricated electrode exhibited good electrochemical performance with low electr...

[ 5 ] - Electrochemical Analysis of Tryptophan using a Nanostructuring Electrode with Multi-walled Carbon Nanotubes and Cetyltrimethylammonium bromide Nanocomposite

Multi-walled carbon nanotubes (MWCNTs) were immobilized on the surface of a glassy carbon electrode (GCE) in the presence of cetyltrimethylammonium bromide (CTAB) to form a MWCNTs-CTAB nanocomposite-modified electrode. The electrocatalytic response of the modified electrode towards tryptophan (Trp) was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The surface...
