摘要：
A simple soft-core model potential is proposed to discuss the self-diffusion of biomolecules in solution. Extensive Brownian-dynamics simulations are performed to obtain the long-time self-diffusion coefficient. Then the simulation results are compared with the experimental data from a unified point of view recently obtained for suspensions of hard spheres. Thus, it is shown that the proposed potential can qualitatively well describe the experimental data.
