Abstract: Two self-assembled bilayer lipid membranes (BLMand C60 contained BLM ) on indium-tin-oxide (ITO) were fabricated and their photoelectric conversion properties were studied. The investigation of the effects of applied voltage, donor and receptor on the photocurrent intensities showed that the anodic photocurrent of BLMs increased with increasing anodic potential and donor concentration; C60 doped in BLMfacilitated the photoinduced electron transfer across bilayer membranes. This novel self assembled ITO/BLMelectrode can provide a simple and mechanically stable model for the study of the photoelectric properties of biomembranes.

Key words: Bilayer lipid membranes, Fullerenes, Photocurrent, Electron transfer
