Ex vivo entrapment and permeation studies. (A) Amount of DEX entrapped per unit area from DS-RLs/DEX hydrogel and DS-FLs/DEX hydrogel. (B) Amount of DEX permeated per unit area from DS-RLs/DEX and DS-FLs/DEX hydrogel, *p < .05 vs DS-RLs/DEX. (C) Fluorescence images of skin treated with DIR-labeled DS-RLs/C6 hydrogel and DIR-labeled DS-FLs/C6 hydrogel at 30 min and 4 h (Scale bars = 200 nm).
