Electrocatalysis by a C60-γ-cyclodextrin (1 : 2) and nafion chemically modified electrode of hemoglobin

Abstract The electrochemical behavior of films of C 60 - γ -cyclodextrin (1 : 2) and Nafion has been studied in an aqueous solution. A reversible surface-confined electroreduction wave and an irreversible electroreduction wave were detected by cyclic voltammetry. It is found that the chemically modified electrode has electrocatalytic activity to hemoglobin.
