This study focuses on the correlation between the dynamics of individual particles in a dense charged colloidal system. By Brownian Dynamics simulation, the nagative number correlation function of these interaction colloids are calculated, which, by further theoretical analysis, help to extract information of the diffusion rate of the individual colloids (at difference time scale) and the interacting length scale between the particles. The simulation provide an effective appraoch of interpretating the results of multi-color fluorescence correlation spectroscpy, which allows particle recognition within a dense system.
