3.5.1. Effects of Different pH on the Size of SeCS Nanoparticles

After dialysis, the system solution pH (6.8) was adjusted to 2, 4, 6, 8, 10 and 12 using 0.1 M sodium hydroxide (NaOH) or 0.1 M hydrochloric acid (HCl). After 10 min, the particle size of SeCS was determined by Malvern Zeizer Nano ZS particle analyzer (Malvern, Worcestershire, UK).
