(a) UV irradiation activates DEAP, generating free radicals which initiate polymerization of AA monomers and BA cross-linkers (b) Addition of ascorbic acid (star) inhibited polymerization of un-encapsulated components (85%) remaining outside liposomes (dots) when added at a molar ratio of 200:1 relative to DEAP; ascorbic acid is a free radical scavenger that is impermeable through the lipid bilayer (c) Upon UV irradiation, 80% of AA monomers and BA cross-linkers were consumed for polymerization within ca.15 min.
