(A) Normalized diffusion coefficients of ions and water molecules to its bulk value (D/D_bulk) as a function of distance r from protein’s and DNA’s heavy atoms²⁴; fitting of these diffusion coefficients by eq 11. (B) Dependence of spherical particle diffusion coefficient from the distance from molecular wall, calculated using hydrodynamic approximation;⁴² radii of spherical particle and cylindrical hole are 2 Å and 10 Å respectively.
