Abstract: A new data analysis method of dynamic light scattering of gels with macromolecules was proposed,in which the inhomogeneity of polymer gels was taken into account.The reliability of the method was verified by measuring the effective diffusion coefficient of Lysozyme in polyacrylamide gels.The dependence of the effective diffusion coefficient of macromolecules on monomer concentration was also observed.
