摘要
The light induced reduction-oxidation process in a Photosystem I (PSI) bio-hybrid electrode has been probed by scanning electrochemical microscopy (SECM). The first simultaneous amperometric photocatalytic responses at both the substrate and the tip electrodes over PSI are reported. The approach curves were recorded as a tip electrode approached PSI films under light and dark conditions. The results reveal that a film of PSI serves as an effective blocking insulator under dark conditions; however, the PSI films were able to regenerate redox species with limited kinetics under illumination. All of these results suggest that PSI film behaves as an integrated photodiode device.
