Mobility of liposomes in fresh rat intestinal mucus at 37 °C. (A) Representative trajectories of particle motion in 1 s. (B) MSD values as a function of time. (C) Typical MSD values for liposomes at 1 s. (D) Distribution of the logarithms of individual particle effective diffusivities $\left(D_{\mathrm{eff}}\right)$ on a timescale of 1 s. The data represent three independent experiments, and each experiment tracks 100 particles. The data are shown as the means ± SD (n = 3). **P < 0.01; ****P < 0.0001.
