摘要：Two kinds of Gemini surfactant monolayer, which showed different hydrophobic property, were selected as adsorption substrates for collagen. The topographic images of collagen were investigated by using an atomic force microscopy (AFM). Their auto-organized nano-structures were influenced by the property of substrate and the process of sample preparation, such as concentration of collagen solution, adsorption time and drying condition. Network-like structures formed on the both Gemini monolayers. With increasing concentration of collagen solution and adsorption time, the density of the network-like structure increased and their strands became wider and the mesh sizes decreased apparently. Contrary to the reference, the network-like structures of collagen also formed on the less hydrophobic Gemini surfactant monolayer even after very short adsorption time, which was considered to result from the more hydrophobic patch on it.
