| Outline of Final Research Achievements |
We examine lipid bilayer membranes as a field of chemical reactions, by estimating their thermal diffusivity, viscosity, and polarity, with time-resolved spectroscopies. Picosecond time-resolved Raman spectroscopy of trans-stilbene solubilized in lipid bilayer membranes reveals that the rate of energy transfer changes when the phospholipid that forms the lipid bilayer or the temperature changes. Picosecond time-resolved fluorescence spectroscopy indicates that there are two environments with viscosity different by 30 to 290 times in the lipid bilayer membranes. We have developed new phospholipids by introducing fluorophores into phosphatidylcholines for examining the properties of lipid bilayer membranes at a fixed depth.
