| Outline of Final Research Achievements |
Biological membranes have uneven physical shapes. By recognizing on the physical shapes, lipids and proteins specifically assemble and disassemble, and realize their sophisticated functions. In this research project, to realize the real-time observations of these biological processes by high-speed AFM, new AFM substrates with sub-micrometer sized holes have been developed on a glass and PDMS surfaces using Focused Ion Beam (FIB) lithography and nanosphere imprinting. Using the AFM substrates developed here, some phenomena and objects depending on the physical shapes of membrane, diffusion of lipid molecules, assembling of a membrane protein as well as a suspended native membrane, were directly visualized.
