Use of Prussian Blue/Conducting Polymer Modified Electrodes for the Detection of Cytochrome C

Abstract

In this work, the development and utilization of a Prussian blue/conducting polymer composite electrode has been investigated. The introduction of a layer of conducting polymer (polypyrrole) enhanced the electroactivity of the outer Prussian blue film. This has been used for improved signal generation for the redox protein cytochrome c. The effect of the thickness of these two film coatings and buffer solution pH has been investigated. The analytical utility has been demonstrated using flow injection analysis.

Palladized aluminum electrode covered by Prussian blue film as an effective transducer for electrocatalytic oxidation and hydrodynamic amperometry of N-acetyl-cysteine and glutathione

“…It was found that PB films have been deposited on glassy carbon [29][30][31][35][36][37][38][39], graphite [30,32,33,39], platinum [40,41] and carbon fiber [28] and also incorporated into polypyrrole [42,43] and carbon paste [44][45][46]. Our group first announced the development of transition metal ferricyanide modified electrodes on the basis of Al substrate [47][48][49][50][51].…”

Synthesis of functional polypyrrole/prussian blue and polypyrrole/Ag composite microtubes by using a reactive template

“…In addition, much effort has been focused on the preparation of noble metal (such as Au and Ag) and conducting polymer composites because of their superior performance as nanocircuits, nanodevices, and nanosensors [26,27]. Although PPy/PB composite films [19,28,29] and PPy/Ag composites [30][31][32] are well documented, the composite nanotubes are rarely reported. Pyrrole monomer can be oxidized by potassium ferricyanide (KHCF) [33] or silver nitrate to form PPy and, PB or Ag [31,32], respectively.…”

Palladized aluminum as a novel substrate for the non-electrolytic preparation of a Prussian Blue film modified electrode

“…In the search for suitable matrices for PB immobilization, it is found that PB films have been deposited on a variety of surfaces, the most being glassy carbon [12,[15][16][17]19,23,24,31,32], graphite [18,20,21,33], platinum [34,35] and carbon fiber [22]. It has been also incorporated into polypyrroles [36,37] and very little attention has been given to carbon paste electrodes modified with PB [14,[38][39][40].…”
