Scaling laws for the early time adsorption kinetics. The determination of the cutoff radius is shown. When the interfacial coverage is limited at an early stage by a diffusive process, a square root dependence with time is obtained for a flat interface. For a sphere, the power law has a 3/2 exponent. In the kinetic regime, a linear dependence is obtained for a Langmuir-type kinetics. The crossovers between the different regimes reveal that for sufficiently small droplets, the adsorption is never diffusion-limited.
