Gelation temperature of injectable chitosan–collagen hydrogel containing different fucoidan concentrations. (a) Temperature sweep tests were performed to determine the exact gelation temperature. The gel point (G′ (dots) > G″ (squares)) is marked with a dashed line. (b) The gelation temperature was plotted for hydrogels without and with 100 µg/mL fucoidan. Experiments were repeated three times (n = 3).
