    • Biomembrane devices by using elastic energy barriers are provided to serve a controllable extracellular membrane system similar to in vivo lipid bilayer, so that the Biomembrane devices are useful for study on membrane proteins under conditions similar to in vivo environment, and for treatment of diseases by using bio-signal transfer control. A method for preparing the biomembrane devices comprises the steps of: (1) forming a geometrical surface micro structure on a base substrate; (2) forming a lipid bilayer having a specific lipid region on the geometrical surface micro structure of base substrate; and (3) optionally treating the lipid bilayer with heat, wherein the specific lipid region is lipid raft; the geometrical surface micro structure of base substrate contains a curved region functioning as an inhibition region of a specific lipid region growth and a flat region functioning as an induction region of a specific lipid region growth, forms difference of elastic energy on the lipid bilayer and is prepared by etching, stamping, light irradiation or deposition. The growth and diffusion of a specific lipid region in the lipid bilayer are controlled by the base substrate with the geometrical surface micro structure.
