Circular Dichroism Spectroelectrochemical and Voltammetric Studies of Vitamin B2

“…In the process of electroreduction, there was no reaction occuring to the chiral centers of VB 2 , so the change of CD spectra is mainly due to the changing of the conjugated system in the flavin chromophore after its receiving two electrons from the electrode. The electroreduction results of VB 2 and the assignment of the electronic transitions which produce different cotton peaks can be further substantiated as follows by the experimental facts and the theoretical calculation [1,28].…”

New method for characterizing electron mediators in microbial systems using a thin-layer twin-working electrode cell

“…Currently, various amperometric and voltammetric techniques have been widely used to detect and evaluate electrochemical properties of redox active entities, including soluble mediators (Dryhurst, 2012 andRoussel et al, 2008). These conventional techniques are typically carried out by using three-electrode systems, whereby oxidation or reduction of the target compound present in the boundary layer of the working electrode (WE) can be precisely controlled and/ or monitored (Compton et al, 2013).…”

Electrochemical Behavior of Thiamine on a Self-Assembled Gold Electrode and Its Square-Wave Voltammetric Determination in Pharmaceutical Preparations

“…In the literature various methods of thiamine determination have been reported, for example, fluorometric, 1-4 spectrophotometric, 5 flow injection analysis [6][7][8][9][10] and electrochemical methods. [11][12][13][14][15] However, the reported methods can cause problems concerning environmental pollution; also, these routine techniques have often not been deficiently sensitive. It is therefore important to establish highly sensitive methods for the determination of ultra trace amounts of thiamine.…”
