摘要：
In this paper an urchinlike MnO2 nanoparticle was synthesized by hydrothermal method and applied to the protein electrochemistry for the first time. By using a carbon ionic liquid electrode (CILE) as the basal electrode, hemoglobin (Hb) was immobilized on the surface of CILE with chitosan (CTS) and MnO2 nanoparticle composite materials. Spectroscopic results indicated that Hb molecules retained its native structure in the composite film. A pair of well-defined redox peaks appeared on the cyclic voltammogram with the formal peak potential as -0....
