Research Abstract |
In this study, we have developed a methodology of detecting interfacial tension and related properties of a planar artificial self-supported lipid membrane, or black lipid membrane (BLM) for studying fluctuations and mechanical/chemical properties of biomembranes. Laser-induced surface deformation spectroscopy was applied by optimizing the refractive indices of two water phases. As a result, measurement of fluctuation and interfacial tension of BLM has been succeeded and their dependence on its compositions and molecular was discussed.
