Construction of stable polymeric vesicles based on azobenzene and beta-cyclodextrin grafted poly(glycerol methacrylate)s for potential applications in colon-specific drug delivery.

Polymeric vesicles constructed from cyclodextrin- and azobenzene-grafted poly(glycidyl methacrylate)s showed excellent stability owing to the multiple host-guest complexation. Upon culturing in Na2S2O4-contained buffer solution, cargo-loaded vesicles disassembled, for potential applications in colon-specific drug delivery.
