Abstract: | Based on a semi-phenomenological Fokker-Planck approach,
we present and discuss a theoretical framework for studying the
transport properties of macromolecules in solution. A formally exact
expression for the diffusion of macromolecules is derived and
utilized in order to show the anomalous character of the
macromolecular diffusion, both at very short times, t→
0, as well as in the asymptotic limit, t→∞.
Numerical computations for 50- and 100-bead macromolecules
demonstrate moreover a `superdiffusive' behaviour at short and
intermediate times when compared with the data from the (Einstein's)
phenomenological theory. |
