Figure 6.
Drug loading and release profile of PFPE/PEI/F127 hydrogel (Hydrogel F) and controls. (A) Resveratrol (model drug) loading in hydrogel F compared to PFPE-free hydrogel containing PEI (Hydrogel G) and pure F127 hydrogel control (Hydrogel H). The presence of unconjugated PEI in PFPE-free hydrogel (Hydrogel G) significantly decreases resveratrol loading compared to cross-linked hydrogel F. (B) The presence of PFPE-PEI emulsion droplets does not significantly affect the resveratrol release profile as compared to pure F127 (Hydrogel H) while both gels show extended release.
