^x Mean values of medians ± SD are represented for 3 independent analyses.

^y The percentage of particles with a minimal feret diameter smaller than 100 nm is represented.

^{a, b} Different letters indicate significantly different mean values by Kruskal-Wallis One Way Analysis of Variance on Ranks (P < 0,05).
