Abstract

Spinacia Oleracea ferredoxin (SOFd) was immobilized on the surface of the multi-walled carbon nanotubes (CNT). The results of UV-Vis spectra and Fourier transform infrared (FT IR) spectra indicated that SOFd retained the essential feature of its secondary structure on the surface of CNT. The cyclic voltammetric results showed that the SOFd on the surface of CNT could undergo effective and stable direct transfer-electron reaction. The cyclic voltammogram was characterized by a well-defined and nearly sym-metrical redox peaks with formal redox potential (E^0') of (－570.4±1.5) mV (vs. SCE, in 0.1 mol/L PBS), which was almost independent on the scan rates and solution pH. The apparent heterogeneous electron transfer rate constant (k_s) for the direct electron-transfer of SOFd was estimated to be (0.73±0.04) s^－1.

Key words: carbon nanotube, chemically modified electrode, ferredoxin, direct electron transfer
