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

<div>Optical micrographs of hydrogels made from CMC 2%: (a) ionotropic gelation with CaCl<sub>2</sub> 1% w/v; (b) ionotropic gelation with CaCl<sub>2</sub> 4.9% w/v; (c) polyelectrolyte complexation with CS 0.01% w/v; (d) combination of ionotropic gelation and polyelectrolyte complexation (CaCl<sub>2</sub> 1% w/w). Scale (a, b) 200x and (c, d) 100x.</div>
