The highly hydrophobic drug docetaxel ( DTXL ) was physically entrapped within the PBS / PBDL copolyester core and the hydrophilic drug doxorubicin hydrochloride ( DOX . HCl ) was chemically conjugated to the reactive PHPMA copolymer shell via hydrazone bonding that allowed its pH - sensitive release .
