Abstract
Hemoglobin (Hb) is immobilized with cadmium sulfide (CdS) nanoparticles (NPs) on pyrolytic graphite (PG) electrode to characterize the electrochemical reactivity and peroxidase activity of the protein. The result demonstrates that fine redox waves of Hb can be achieved after this protein is entrapped in CdS NPs. Meanwhile, the protein can exhibit nice catalytic activity towards hydrogen peroxide (H2O2). Linear relationship between the reductive peak current and the H2O2 concentration has been obtained from 5.0 Ã 10â 6 to 4.0 Ã 10â 4 mol/L, on the basis of which a new kind of H2O2 biosensor might be developed in the future.
