Article: Direct electrochemistry and electrocatalysis of hemoglobin on an indium tin oxide electrode modified with implanted carboxy ions
[show abstract] [hide abstract]
ABSTRACT: A carboxyl ion implantation-modified indium tin oxide (COOH/ITO) electrode was prepared, and the existence of a carboxyl group on the electrode was verified by X-ray photoelectron spectroscopy (XPS). Hemoglobin (Hb) was immobilized on the electrode, and cyclic voltammetric techniques were employed to evaluate the electrochemical behavior of Hb. Based on the activity of Hb on the COOH/ITO electrode towards the reduction of hydrogen peroxide, a mediator-free H2O2 biosensor was constructed, which showed a linear range from 1.0μM to 200.0μM with a detection limit of 0.3μM (S/N = 3).Microchimica Acta 04/2012; 167(1):41-46. · 3.03 Impact Factor
