Size distribution of particles in control and sonicated samples. An area within 30 μm from the top of each pellet was sampled and the length (major axis) of PSDs and particles, ~ 40 nm in length and bigger, of similar electron density were measured in electron micrographs from control, sonicated and sonicated + samples. The differences between the control vs. either sonicated or sonicated + samples were statistically significant (P < 0.0001 via ANOVA for means, and Wicoxon test for medians) whereas no statistically significant differences were found between sonicated vs sonicated+ samples using the same statistics
