Rheological and structural properties of the Fmoc–DOPA–DOPA hydrogelator. Strain sweep (a) and frequency sweep (b) characterization of 5 mg/mL in situ-formed hydrogel at 25 °C. (c) Gelation kinetics of Fmoc–DOPA–DOPA at different concentrations at 25 °C. (d) Gelation kinetics of 5 mg/mL Fmoc–DOPA–DOPA at different temperatures. (e) Kinetics of absorbance at 405 nm at two concentrations and macroscopic visualization of the preparation. (f) HR-SEM micrographs of the turbid peptide solution immediately after inducing the assembly process (left and center panels) and of the semitransparent gel after 2 h of incubation (right panel).
