The angle resolved laser light scattering technique has been used to study aggregation and time evolution of clusters of blood platelets. The radial distribution function of the form tex2html_wrap_inline2750 (where D is the fractal dimension) is assumed for the clusters and the structure factor determined. Taking guess values for fractal dimension and radius of gyration from the experiment, a chi square fitting has been done for the scattered intensities. Clusters formed have analysed for their polydispersity. The poly dispersed radius of gyration and the structure factor are determined. The time evolution of clusters has also been discussed.
