Dynamic oscillatory rheological characterization of peptide hydrogel P (formed by mixing two oppositely charged undecapeptides KWK and EWE). (A) Time-sweep monitoring of gelation kinetics; plateau G′ ~ 90 kPa. (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); yield strain value γ ~ 3–4 %; complete break of hydrogel at γ ~ 6 %. Elastic modulus G′ (open circles); viscous modulus G″ (solid circles); shear modulus G (triangles).
