We use dynamic light scattering to measure the time-dependent increase of the average hydrodynamic radius of colloidal silica particles in the presence of salt. This increase appears to be linear in time up to twice the radius of unaggregated particles. The method is a very useful tool in monitoring
Block copolymers that have both adsorbing and nonadsorbing blocks can be used to stabilize colloidal dispersions. However, they can also induce an attraction between two particles by forming bridges between the surfaces. In this paper we investigate when such an attraction occurs and how its magnitu
