Oxovanadium(V/IV) Complexes as Redox Mediators for Biofuel Cells: Physical, Magnetic, and Electrochemical Characterization, DFT and Molecular Docking

Based on the potential redox and catalytic ability of oxovanadium complexes, our goal was to characterize physical properties two such complexes be used as mediators for laccase. Computational studies, TD-DFT calculations docking simulations were performed elucidate interaction between laccase anionic (aquabis(oxalato)oxidovanadate(IV) (1) bis(oxalato)dioxidovanadate(V)) (2), respectively. Electrochemical measurements carried out anion 1 2 docked into compared alone, showing changes in oxidation-reduction current value, especially with 2. Since both internal tiny magnetic fields ferromagnetic catalysts external applied found previous investigations constitute effective ways improve oxygen transfer rate, susceptibility measured. A valence change proneness confirmed higher 2, which is accordance electrochemical results.
