关键字：Poly(ethylene glycol)-b-poly(ε-caprolactone); doxorubicin; drug delivery; micelles; crystallinity; drug-polymer compatibility
This study aimed to optimize poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) based amphiphilic block copolymers for achieving a better micellar drug delivery system (DDS) with improved solubilization and delivery of doxorubicin (DOX). Firstly, the Flory-Huggins interaction parameters between DOX and the core-forming segments [i.e. poly(ε-caprolactone) (PCL) and poly[(&epsi...
