A surface structural comparison of composite film of bacteriorhodopsin (BR) and phosphatidylcoline (PC) fabricated on a layered fatty acid film on a substrate of amorphous silicon dioxide (a-SiO 2 ), crystal silicon dioxide (c-SiO 2 ), or hydrogenated amorphous silicon (a-Si:H) was conducted to investigate the effect of substrate structure on the Langmuir-Blodgett (LB) film fabrication of membrane protein by direct force microscopy (DFM) measurement. On the a-SiO 2 substrate, a hexagonal crystal structure of BR and PC with a size of 0.5 mm was observed. However, on the c-SiO 2 or a-Si:H substrate, the surface structural features of the composite LB films differed from each other on the shape of assemblies in themselves. In spite of the presence of fatty acid layers, the assemby of BR and PC depends on the structure of the bottom substrate.
