Colloidal dispersions were characterized in terms of particle size, polydispersity index (PdI), and zeta potential (ZP) using a Zetasizer Nano ZS (Malvern Instruments Ltd., Worcestershire, United Kingdom). In particular, the size and PdI were fitted to the third-order cumulant expression and at a back scattering angle of 173° [21,22], while zeta potential is related to electrophoretic mobility using Smoluchowsky equations [23]. The samples were diluted with a proper aqueous solution to avoid multi-scattering phenomena.

All measurements are the mean of three different experiments ± standard deviation.
