To prove the ergodic theorem experimentally the diffusivities of guest molecules inside a nanostructured porous glass were measured by using two conceptually different approaches under identical conditions. The data obtained through the direct observation of dye-molecule diffusion by single-molecule tracking experiments (red circles) was in perfect agreement with the ensemble value obtained in pulsed-field gradient NMR experiments (black squares).
