Dynamic oscillatory rheological characterization of polysaccharide network CA (chitosan + alginate). (A) Time-sweep monitoring of gelation kinetics; plateau G′ ~ 100 Pa; final δ ~ 30°. (B) Frequency-sweep after viscoelastic modulus reached plateau, max G″ at ω ~ 20 rad/sec. (C) Strain-sweep performed after frequency-sweep and 3 hrs of equilibrating time sweep (see, Materials and Methods). Elastic modulus G′ (open circles); viscous modulus G″ (solid circles); shear modulus G (triangles).
