Figure 5.

Comparison of experimental data and a calculated MSD for a particle with a diameter of 200 nm, indicated as a red dashed line. A membrane distance of L = 0.25 μm, with D₀ = 0.2 μm²s⁻¹, p_M = 0.05, and therefore a ratio of D_eff/D₀ = 0.02 was used. In the background, a figure taken from (13) with experimental data for PS particles in human sputum from CF patients (solid lines) is shown. The transient time regime of subdiffusion is marked.
