Abstract

The formation of molecular hetero-film consisting of green fluorescence protein (GFP) and viologen LB film using the electrophoretic sedimentation technique (EPS) is investigated. The fabrication condition by EPS such as the exposure voltage affects the topology and photoresponse of GFP films. Based on the surface topology measured by atomic force microscopy (AFM), the optimal electric field for the fabrication of GFP film was found as 4.5V.
