Transport of COOH- and PEG-modified polystyrene particles in fresh, human cervicovaginal mucus (CVM). Ensemble-averaged geometric mean square displacements (<MSD>) as a function of time scale for (A) COOH- and (B) PEG-modified polystyrene particles in human CVM. Comparison of average Deff at a time scale of 1 s in water (W) vs. CVM of subfractions of (C) COOH- and (D) PEG-modified particles, from fastest to slowest. Theoretical Deff for same-sized particles in water is shown as W. The dashed black line at <Deff> = 1 × 10−4 signifies the microscope’s resolution. Data represent ensemble average of three experiments, with n ≥ 120 particles for each experiment. Figure obtained from [17].
