| Summary: | The systems considered here are mixtures of neutral rods and spheres in solution, for which I aim to describe the rods’ diffusion coefficient. Several situations are studied according to the partial volume fractions and relative sizes between the two types of colloids. Using scaling analyses, I either obtain the translational or the rotational diffusion coefficient. Some of my predictions are compared with available experimental and numerical data, showing good agreement. The relevance of this work is to provide models that capture the main features concerning the diffusion of rods in mixed colloidal solutions and make contact with a much more intricate problem of diffusion in crowded media, such as the interior of the cytoplasm. |
