Lateral diffusion and two dimensional organization of lipids and proteins are crucial fundamental processes in cell membrane reactions such as the transportation of materials, information and energy in and out of cells. Here I introduce our works on the dynamic processes of lipids and proteins in and on supported lipid bilayers (SLBs), one of artificial lipid membrane systems formed at solid-liquid interfaces [1,2]. I also show our recent experimental results about the lipid membranes on graphene oxide from the view point of the bio-interface on device materials.
