| Research Abstract |
An electron transfer at lipid membrane/water interface was observed by a slab optical waveguide spectroscopy. A lipid membrane was formed on a thin glass plate, into which an excitation light was introduced. Thus, an absorption spectrum of the inside of lipid membrane was selectively observed by an evanescent wave of the guiding light. Curcumin, on of the lipophilic antioxidants, was distributed into the lipid membrane, and the oxidation, i.e. electron transfer reaction through the lipid membrane/water interface between H_2O_2 dissolved in water was observed.
