In this paper, electrochemical characteristics of diamond and carbon nanowalls (CNWs) as well as various composites made of these carbon materials will be reported and compared for biosensor applications.
Cyclic voltammetry (CV) is applied to measure electrochemical reactions of carbon electrodes in 0.1M H2SO4 solution and 0.01M Fe(CN)6-3/-4+0.1M KCl aqueous solution. The cyclic voltammetric curves provide information about electron transfer kinetics and thermodynamics on the electrode surface.
Diamond electrodes possess low and stable background currents, wide working potential windows, and good physical and chemical stability. CNWs contain nano-meter sharp edges, high aspect ratios, excellent electrical and thermal conductivities and good chemical stability. They extend in a two-dimensional wall-like network and create a very large effective surface area desirable for electrochemical electrodes. These materials have been deposited by means of Direct Current Plasma Enhanced Chemical Vapor Deposition (DC-PECVD), Microwave Plasma Enhanced Chemical Vapor Deposition (MW-PECVD) and Hot Filament Chemical Vapor Deposition in gas mixtures of methane and hydrogen.
Electrochemical characteristics are correlated with surface morphologies and crystalline properties of carbon films which are examined by Scanning Electron Microscope (SEM) and Raman spectroscopy (Raman), respectively. This class of carbons and carbon composite electrodes are promising for biosensor applications.
