1.3.4 Surface charge: Zeta potential
Surface charges of nanoparticles were measured with Zetasizer ZS
(Malvern Panalytica, Malvern, UK). 1000 µL of each sample were place in
the disposable folded capillary cells for the measurement of zeta
potential (DTS1070). Each sample was tested 3 times over the course of
15 runs.
