Dynamic oscillatory rheological characterization of mixed hydrogel CAP (formed by incorporation of two oppositely charged undecapeptides KWK and EWE into existing CA network). (A) Time-sweep monitoring of gelation kinetics; plateau G′ ~ 10 kPa; final δ ~ 17°. (B) Frequency-sweep after viscoelastic modulus reached plateau. (C) Strain-sweep performed after frequency-sweep and 3 hrs of equilibrating time-sweep (see, Materials and Methods); retaining δ ~ 25–30° even at strain values γ ~ 100 %. Elastic modulus G′ (open circles); viscous modulus G″ (solid circles); shear modulus G (triangles).
