A new analytical expression for the treatment of the kinetic turbidimetry of patchy colloids aggregation was derived and verified. Diffusion-limited aggregation rate constants of chemically-anisotropic reactants with several small active sites were presented. Light scattering cross sections of the aggregates (of fractal structure) were calculated using the superposition T-matrix method. Gillespie method was applied to calculate stochastic kinetics of the aggregation (which is essential at low number of active sites on particles). A significant effect of the low number of active sites per particle on the turbimetric kinetics was found.
