제목 Synthesis of Ester Diselenide-Containing Crosslinker for Core Crosslinked PEO-b-PFMA Micelles
초록 In this work, we sucsessfully synthesized the ester diselenide-containing crosslinker. A well-defined amphiphilic block copolymer, poly (ethylene oxide)-b-(poly (furfuryl methacrylate) (PEO-b-PFMA) was prepared by single electron transfer living radical polymerization (SET-LRP). The block copolymer formed sub-100 nm micelles in water with PEO as a shell and PFMA as a core. Diels-Alder click type reaction was employed to form core-crosslinked micelles using a diselenide-containing crosslinker. The stability of core-crosslinked micelles under reductive-oxidative condition was also investigated. The diselenide crosslinked micelles displayed good stability against extensive dilution but decomposed under the presence of hydrogen peroxide or glutathione. The redox-responsive core-crosslinked micelles can be a promising for drug delivery applications
