We study the aggregation of aqueous gold colloids and apply modern scaling methods to interpret our results. We find that there are two regimes of aggregation, each with different rate-limiting physics, depending on the sticking probability of the individual colloidal particles. Each regime is distinguished by the fractal dimension of the resultant clusters, the aggregation dynamics and the cluster-mass distribution. The two regimes are diffusion-limited cluster aggregation and reaction-limited aggregation; and the two represent the two limiting universality classes for kinetic cluster-cluster aggregation.
