Analysis of the electron transfer at lipid membrane/water interface by a slab optical waveguide spectroscopy

用平板光波导谱观察到脂膜/水界面的电子转移。在薄玻璃板上形成一层类脂膜，并引入激发光。因此，通过导光的消逝波选择性地观察到脂膜内部的吸收光谱。在脂类抗氧化剂中，姜黄素被分散到脂膜中，观察到H_2O_2溶于水后通过脂膜/水界面的电子转移反应。

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.
