Characterization of cationic liposomes and hydrogels. A) TEM image of unloaded liposomes (Lipo). B) TEM image of resveratrol-loaded cationic liposomes (Res@SA-Lipo). C) Particle size distribution curve and polydispersity index (PDI) value of Lipo. D) Particle size distribution curve and polydispersity index (PDI) value of Res@SA-Lipo. E) Macroscopic images of hydrogels formulated with varying concentrations of liposomes (Lipo0: 0 wt%, Lipo1.25: 0.125 wt%, Lipo2.5: 0.25 wt%, Lipo5z: 0.5 wt%). F) Zeta potential of Lipo and Res@SA-Lipo. G) Compressive stress-strain curve of hydrogels under cyclic loading. H) Compressive stress-strain curve of hydrogels under continuous loading. I) Maximum compressive load of the different hydrogels. J) Compression modulus of hydrogels. K) Maximum compressive strain of hydrogels. (n = 3 for each group), (∗P < 0.05; NS: not significant).
