摘要

New cationic, thermo-sensitive andrnbiodegradable PLLA-PEOz-PLLA triblock copolymersrnwere synthesized by ring-opening polymerization.rnThe prepared “flower-like” nanoparticles showed thernability to change their core/shell structure whilernchanging pH values. Drugs was protected in cores ofrnmicelles after intravenous administration, andrnreleased as being endocytosed into endosome inrntumor cells.
