제목 Doubly-Responsive Polymersomes for Smart Insulin Delivery Vehicles under Physiological Conditions
초록 Organoboronic acid-containing polymers and block copolymers have attracted recent attention because of their ability to recognized important natural diol compounds such as saccharides and nucleotides. We synthesized the new monosaccharide-responsive polymers comprised of random copolymers of styrene-boroxole and oligo(ethylene glycol)-functionalized styrene (OEG-St). The block copolymers self-assembled into glucose-responsive micelles and vesicles. Due to the presence of solubilizing groups surrounding the glucose-responsive boroxole units in the polymer backbone, the resulting copolymers showed glucose-responsive behavior at lower glucose concentration compared to the glucose level for the responsive behavior of PBOx homopolymer. Vesicles showed glucose-triggered disassembly under physiologically relevant pH conditions and glucose levels (10 ~ 20 mM).
