| Outline of Final Research Achievements |
Lipid bilayer is one of the important cellular components and indispensable not only for separation between inner region and outer region of cells but also for the acute structures and functions of membrane proteins. Because the cellular membrane is composed of various lipids and protein, biophysical analyses of lipid and membrane protein function require to form artificial lipid bilayer easily. Whereas devices for formation of lipid bilayer have been proposed, these devices cannot form optically-observable lipid bilayer repeatedly. In this research project, we developed the rotational device for the repetitive formation of lipid bilayer by using MEMS technology. We confirmed the formation of lipid bilayer by measurement of bilayer thickness and observed the function of one of membrane protein, alpha-hemolysin. Because this device enables us to form the lipid bilayer repeatedly, it is thought to analyze the function of membrane and membrane protein statistically.
