Polyelectrolyte Complexation versus Ionotropic Gelation for Chitosan-Based Hydrogels with Carboxymethylcellulose, Carboxymethyl Starch, and Alginic Acid

Figure 5

Comparison of hydrogel beads made from CMS 3.2% by (a) ionotropic gelation with CaCl2 4.9% w/v, (b) polyelectrolyte complexation with CS 0.01% w/v, and (c) combination of ionotropic gelation and polyelectrolyte complexation (CaCl2 1% w/w). Scale 100x.
