项目摘要
The aim of the research is to develop the analytical tools to measure the dynamics at the interface related to the soft materials such as liquid interfaces and biological membranes. Quasi-elastic laser scattering (QELS) has been applied to the study on the surface of imidazolium salts (room temperature ionic liquids) - water system. The surface stress, taken by QELS, reflects the molecular behavior at the surface. The change of the surface stress has been measured and its dependence on molar ratio of imidazolium salts to water can be clarified. It has been concluded that the transient interaction of cations and anions takes place. Further, we have succeeded in the measurement of the interfacial stress of the black lipid membrane, which consisted of two lipid layers. The addition of the surfactants induces the change of the membrane structure and it is found that QELS is a powerful tool to take the structural change of the black lipid membranes.As another analytical tool, Brewster angle microscope has been developed using a high N.A. objective lens. The Brewster angle reflection takes place in the objective lens, so that the lateral resolution is enhanced up to less than 1 μm. Combined with the total internal reflection fluorescence microscope, it has been applied to the study on the phase transformation of lipid membrane.
本研究的目的是发展分析工具,以测量与液体界面和生物膜等软材料相关的界面处的动力学。采用准弹性激光散射(QELS)方法研究了咪唑盐(室温离子液体)-水体系的表面。由QELS获得的表面应力反映了表面处的分子行为。测量了表面应力的变化,并阐明了表面应力与咪唑盐与水的摩尔比的关系。结果表明,阳离子和阴离子的相互作用是瞬时的。此外,我们已经成功地在黑色的脂质膜,其中包括两个脂质层的界面应力的测量。表面活性剂的加入引起了膜结构的变化,QELS是一种观察黑色脂质膜结构变化的有力工具。物镜透镜。在物镜透镜中发生布鲁斯特角反射,使横向分辨率提高到1 μm以下。与全内反射荧光显微镜相结合,应用于脂膜相变的研究。
