Tuning the redox potential of riboflavin by zirconium phosphate in carbon paste electrodes.

A Malinauskas1, T Ruzgas, L Gorton.   

Abstract

Modified carbon paste electrodes were prepared by inclusion of riboflavin together with zirconium phosphate (ZrP) into carbon paste. The midpoint potential for riboflavin in this electrode was found to be -0.259 V vs. SCE and shifted by 0.207 V to the positive direction, as compared to carbon paste electrode not containing ZrP. The electrode prepared was shown to electrocatalyse the anodic oxidation of the coenzyme NADH in the potential range of 0.0 to 0.25 V.
