Mixed ligand copper(II) complexes, viz., [Cu(Br-SAA)(ImH)], [Cu(Br-SAA)(MeImH)], [Cu(Br-SAA)(EtImH)], [Cu(Br-SAA)(BenzImH)] and [Cu(Br-SAA)(MebenzImH)], where Br-SAA = 5-bromosalicylideneanthranilic acid, ImH = imidazole, MeImH = 2-methyl imidazole, EtImH = 2-ethyl imidazole, BenzImH = benzimidazole, MebenzImH = 2-methyl benzimidazole are synthesized and characterized by elemental analysis, mol...

The potential use of hydrazine sulfate was examined for the catalytic reduction of enzymatically generated H2O2 in a biosensor system. The performance of the hydrazine-based sensor was compared with an HRP-based glucose sensor as a model of a biosensor. Hydrazine and HRP were covalently immobilized onto a conducting polymer layer with glucose oxidase. The direct electron transfer reactions of t...

Nitroxide radical polymers (NRPs) are widely used as electroactive materials in a range of electrochemical applications, however, their preparation can be complex. Polyamine Immobilised Piperidinyl Oxyl (PIPO) is commercially available, well-defined, NRP whose properties have not been explored to date. Cyclic voltammetric (CV) studies demonstrate the electroactivity PIPO organic electrolytes, d...

Surfactant modified carbon nanotube paste electrode is prepared as electrochemical sensor with high sensitivity responding to mitoxantrone (MTX). Electrochemical oxidation of MTX is investigated in buffered solution by cyclic voltammetry that is found very sensitive method for detection of MTX. It is shown that the sodium dodecyl sulfate modified carbon nanotube paste electrode (SDSMCNTPE) give...

Titania nanotube (TNT) arrays were fabricated by anodic oxidation of titanium foil in various electrolytes and were calcined in dry nitrogen at various temperatures. The morphology, crystallinity, and chemical composition of TNT arrays were studied by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). Electrochemical impedance spectroscopy (EIS) was employed to investigate...

BACKGROUND Support vector regression (SVR) and Gaussian process regression (GPR) were used for the analysis of electroanalytical experimental data to estimate diffusion coefficients. RESULTS For simulated cyclic voltammograms based on the EC, Eqr, and EqrC mechanisms these regression algorithms in combination with nonlinear kernel/covariance functions yielded diffusion coefficients with highe...

Significant difference was observed for the simultaneous detection of dopamine (DA), ascorbic acid (AA), and uric acid (UA) mixture using nitrogen incorporated diamond nanowire (DNW) film electrodes grown by microwave plasma enhanced chemical vapor deposition. For the simultaneous sensing of ternary mixtures of DA, AA, and UA, well-separated voltammetric peaks are obtained using DNW film electr...
