|Outline of Final Research Achievements
We developed a system of the confocal dynamic light scattering for measurement size, shape, and concentration of particles suspended in water. A laser beam is introduced to an inverted microscope and is focused on a sample. Scattered light is coupled to a optical-fiber and detected by a photomultiplier tube, and then, the temporal correlation function of scattered light is calculated by a correlator. We showed the developed system can be estimate a size and concentration of particles form results of measurement of polystyrene latex beads. The developed system can be applied to the mixture of two kinds of particles. We also successfully estimated the size and concentration of Bovine serum albumin protein.
