2.4.1. Sodium Chloride Stability

Freshly prepared quercetin-loaded HZ, HZ-chi and HZ-chi/pec particles were exposed to 50, 100, 200, 300, 400, 500 mM sodium chloride under continuously mixing for 30 min followed by a 5 min rest [8]. Particle size and ζ-potential were measured, as mentioned above in Section 2.3.1.
