Fluidity, swelling and biodegradation test. (a) Viscosity values of GNP_GH were slightly higher than NC_GH. GNP_GH groups were considered as injectable systems. (b) NC_GH groups were not stable in PBS solution. Meanwhile, GNP_GH groups exhibited a good swelling ratio (> 100%) after 1 day of PBS exposure. (c) GNP_GH groups revealed high injectability (>90%). (d) NC_GH groups were not stable in the enzyme environment and GNP_GH groups were resistant against collagenase degradation. * represented significant difference (p ˂ 0.05, n = 3, N = 3).
