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 
(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.
