Size distribution and ζ-potential of the NBMs. A Hydrodynamic diameter (dH) distribution of the samples in water (100 µg/ml), evaluated by DLS. Each line represents the mean values of 15 measurements that were obtained in three independent experiments. ± SD; B ζ-potential versus pH of the samples evaluated by ELS; C, D Size distribution of C LSNPs and D HNPs evaluated by FPIA. The concentration is reported as the number of micrometric particles
