Electrochemical investigation of carbon nanotube nanoweb architecture in biological media

Journal Article


Abstract


  • The as-synthesised carbon nanotube nanoweb modified carbon fibre paper (CNT-NW/CFP) was investigated to study the effect of surface protein adsorption in electrochemical activities using immunoglobulin G (IgG) and human serum albumin (HSA). Detail chemical characterisation was carried out using 125I radiolabeling, cyclic vltammetry and electrochemical impedance spectroscopy. Both HSA and IgG were adsorbed onto the electrode at levels of approximately 120mg/m2. Cyclic voltammetry indicated that the surface-adsorbed protein had a detrimental effect on oxidation/reduction of ferri/ferricyanide whilst EIS spectra revealed a slight increase in impedance and decrease in capacitance.
