Characterization of self-assembling IIZK peptide biomaterial. (A) Schematic representation of the hydrogel formation. (B) CD spectra. (C) Morphology of self-assembled peptide nanofiber in an SEM micrograph of the nanofibrous peptide network. (D) A Cryo-TEM micrograph of peptide nanofibers with different diameters. (E-G) Rheological characterization of IIZK at 1 mg/mL and 10 mg/mL in 1x PBS. Characterization of the storage (G’) and loss (G’’) modulus of IIZK at 1 mg/mL and 10 mg/mL in 1X PBS; (E) frequency sweep measurements at 0.1% strain and (F) amplitude sweep measurements at 1 rad/s are shown. (G) The stiffness of hydrogel is determined from the G’ value of the linear viscoelastic range of the amplitude sweep test
