Electrochemical Synthesis of Prussian Blue in Conducting Poly (Vinylferrocene) Film

In this study, preparation of prussion blue (PB) and poly(vinylferrocene) PVF modified disposable pencil graphite electrode (PGE) by formation of PB directly inside the iron-containing PVF is described. The modified electrode has the potential to be used for biosensor studies combining the advantages of PB and PVF mediators. Formation of PB inside the polymer has been confirmed by cyclic voltammetry. Furthermore, experimental studies showed that the modified PGE had electrocatalytic activity towards hydrogen peroxide (H2O2) reduction and thus can be used for fabrication of an amperometric H2O2 biosenso
