dH: hydrodynamic diameter, PdI: polydispersity index, ζ: zeta potential, σ: specific conductance.

Note: 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.
