Research Abstract

The construction of the evanescent wave light scattering microscope (EVLSM) proved successful by the use of a novel technique combining the evanescent wave and the dynamic light scattering techniques. The dynamic and static characteristics of a polystyrene latex particle in dispersion interacting with a glass surface were studied by this technique. The dynamic behavior of the thermal vibration of the particle in a potential well created by electrostatic interaction between the particle and glass and gravity was clearly and quantitatively estimated, in addition to the estimation of the potential profile itself. The potential minimum became shallower with increasing added salt concentration, It was also clearly observed that the vibrational motion of the particle in the well became large in amplitude and the probability of the occurrence of the large vibration became large with increasing salt concentration. The potential profile of interaction between a charged liposome particle and glass surface was futhermore estimated directly by EVLSM, which can measure the distance between the particle and surface as a function of time at intervals in the order of less than ins, This new EVLSM technique was as well applied to the system between polystyrene latex particle and chemically-modified glass surface. Such information on the dynamics is essential for the correct understanding of the interaction potential. The EVLSM method is shown to be a very powerful technique for the estimation of not only the potential profilebut also dynamic characteristics.
