TEM images of EVE loaded HA/CS NPs, EVE-2_4 (A) and EVE-2_7 (B). (C) In vitro EVE release from EVE-2_4 (blue line) and EVE-2_7 (black line), 100 μg of NPs was suspended in 0.01M PBS with 1% w/v Tween 20 pH 7.4. NPs release behavior is compared to EVE raw material dissolution profile (orange line). Insert: EVE release profiles between 0 and 8 h of incubation.
