Electrochemical Characterization of the Assembled Recombinant Ferredoxin for the Molecular Electronic Device |
| 초록 |
Electrochemical characterization of recombinant ferredoxin was investigated on a gold electrode in order to develop a molecular bioelectronic device. The recombinant ferredoxin, which was designed to have thiol (-SH) groups by site-directed mutagenesis, was immobilized on top of flame-annealed gold-ball microelectrode by self-assembly method and its molecular configuration was investigated with atomic force microscopy. Cyclic voltammetry showed that the redox potential of the immobilized ferredoxin has a formal potential value of -320 mV (vs. Ag/AgCl).
