Abbreviations: n/d measurement not determined, d H hydrodynamic diameter, PdI polydispersity index, ζ zeta potential, σ specific conductance, ρ agg effective density. Values represent the mean (± SD) of a triplicate reading. Footnote: the average diameters obtained from DLS characterization are derived from the intensity-weighted distributions based on the intensity of light scattered by the particle
