Cyclic Voltammetry: Simulation And Analysis Of Reaction Mechanisms
TL;DR: In this article, the reduction potential and electrode kinetics of cyclic Voltammetric experiments are discussed. But they do not consider the effect of the number of electrons in the system.
Journal ArticleDOI
Simultaneous determination of dopamine, ascorbic acid, and uric acid using carbon ionic liquid electrode
TL;DR: The results show that carbon ionic liquid electrode (CILE) reduces the overpotential of DA, AA, and UA oxidation, without showing any fouling effect due to the deposition of their oxidized products.

Simultaneous voltammetric detection of dopamine and uric acid at their physiological level in the presence of ascorbic acid using poly(acrylic acid)-multiwalled carbon-nanotube composite-covered glassy-carbon electrode
TL;DR: The use of poly(acrylic acid) (PAA)-multiwalled carbon-nanotubes (MWNTs) composite-coated glassy-carbon disk electrode (GCE) for the simultaneous determination of physiological level dopamine and uric acid in the presence of an excess of ascorbic acid (AA) in a pH 7.4 phosphate-buffered solution found it possible to detect lower level UA.
