Square-wave voltammetry of surface redox reactions is considered as an adequate model for a protein-film voltammetric setup. Here we develop a theoretical approach to analyze the effects of temperature on square-wave voltammograms. The performed simulations address the surface redox reactions featuring slow, modest and fast electron transfer. The theoretical calculations show that the temperatu...
Reversible voltammograms and a voltammetry half-wave potential versus solution pH diagram are described for a protein tyrosine radical. This work required a de novo designed tyrosine-radical protein displaying a unique combination of structural and electrochemical properties. The α(3)Y protein is structurally stable across a broad pH range. The redox-active tyrosine Y32 resides in a desolvated ...
Cavity MicroElectrodes (CMEs) offer a valuable platform to evaluate the electrocatalytic performance of micro-and nano-particulate materials. The technical factors and physicochemical processes affecting electrochemical response at CMEs are be recognized, specifically, accessibility redox species electrocatalyst surface. With this aim, voltammetric is investigated through joint experimental the...
The electrochemical behavior of sanguinarine, a quaternary benzophenanthridine glycoside alkaloid with antimicrobial, anti-inflammatory, antioxidant and/or immune-stimulatory activities, was studied at a glassy carbon electrode using cyclic, differential pulse, and square wave voltammetry. The oxidation of sanguinarine is a quasireversible, diffusion-controlled process and occurred in a cascade...
We report on the synthesis of complexes hav ing two equiva lent redox active 2,5-dimethylazafe rrocenyl entities connected by heteroaryl (heteroaryl = thiophenyl, bithiophenyl and pyridyl) bridges. The new compounds have been investigated by various electrochemical techniques including cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SW) and were found ...
