(a) Schematics of the chemical crosslinking of GPG nanofibers. (b) Chemical structure of genipin. (c) Change in the appearance of hydrogels by the addition of genipin solution. The supernatant solutions were removed in the photographs at 7 d. (d) SDS–PAGE of GPG1 and GPG3 gels after reacting with genipin for 7 d. (e,f) Effects of genipin crosslinking on the rheological properties of hydrogels containing (e) GPG1 and (f) GPG3 nanofibers at 0.5 wt% as a function of strain. The moduli of GPG1 gel at 1 d and GPG3 gel at 7 d in Figure 3a are re-plotted as references. (g,h) step-strain sweep measurements of (g) GPG1 and (h) GPG3 gels after genipin treatment.
