Preparation and Characterization of Sodium Alginate/Chitosan Composite Nanoparticles Loaded with Chondroitin Sulfate

Figure 5

Size distributions of the SA/chitosan particles loaded with CS measured at different times: (a) after 1 h; (b) after 3 h (the sample was prepared at the collected distance of 6 cm, the stirring rate of 800 rpm, the flow rate of 0.6 mL/h, and applied voltage of 16 kV; the weight ratio of SA to CS was 5 : 1).
