Parallelized 3D diffusion in dilute and crowded conditions. a Trajectories of five molecules diffusing across lattice subdomains. b Mean-squared displacements (MSDs) of molecules diffusing in a sparsely populated compartment. c MSDs of molecules diffusing in crowded conditions. D₀ is the diffusion coefficient specified in the model, whereas D is effective rate fitted to the resulting MSD. The fraction of voxels occupied by immobile crowder molecules are indicated by ϕ
