摘要
The immobilization of cytochrome c (Cyt-c) in ordered mesoporous niobium oxide thin films is investigated for the first time. The direct electrochemical behavior of Cyt-c assembled onto the. inorganic matrix (see Figure) and the electrocatalytic properties of this assembly are studied. The results open a new doorway for the application of niobium oxides as bioanalytical devices.
