In this work, a tunicate-inspired gelatin-based hydrogel is prepared by simply mixing 2,3,4-trihydroxybenzaldehyde (THB)-tethered gelatin solution with a small amount of Fe3+ ions via the Schiff-base reaction and simultaneous formation of hexavalent Fe-complexes. The resulting hydrogel (termed GelTHB-Fe) exhibits not
