Curcumin release from PPS microparticles was ROS dose-dependent and on demand. A) In vitro release of curcumin from PPS microspheres exposed to temporally-constant H2O2 concentrations ranging from 0 mM to 3 wt% (882 mM) showed H2O2 dose-dependent release. B) In vitro release of curcumin from PPS microspheres with intermittent exposure to 0.1 mM, 1 mM, and 2 mM SIN-1 showed SIN-1 dose-dependent, on demand release during temporal phases when SIN-1 was present. n=3 for all samples.
