Over the past several years, using Stokesian dynamics, progress has been made in simulating coarse grained molecular models of the cytoplasm.

The kinetics of irreversible adsorption of spherical particles onto a flat surface is theoretically studied. Previous models, in which hydrodynamic interactions were disregarded, predicted a power-law behavior t<SUP>-2/3</SUP> for the time dependence of the coverage of the surface near saturation. Experiments, however, are in agreement with a power-law behavior of the form t<SUP>-1/2</SUP>.
