Individual and sequential adsorption of the anionic surfactant sodium dodecyl sulfate (SDS) and the nonionic surfactant Triton X-100 on cationic and anionic polystyrene latexes has been examined. Both latex samples, although charged differently (-16.2 and +11.

We report measurements on the aggregation processes in a colloidal suspension of polystyrene particles covered with F(ab')2 (immunoglobulin IgG fragment) performed by static and dynamic light scattering. In order to study the cluster morphology of aggregates, the fractal dimension is obtained from the dependence of the scattered intensity on the scattering wave number. The stability domains of bare and protein-coated polystyrene particles were examined by plotting the stability ratio as a function of electrolyte concentration.
