Morphological characterization of HPPDC nanoparticles. TEM images of PPDC nanocores (a) and HPPDC nanoparticles (c). Size distributions of PPDC nanocores (b) and HPPDC nanoparticles (d). The weight ratio of ssPBAE/PLGA in PPDC nancores was 3/1 and the weight ratio of HA/PPDC nanocores in HPPDC nanoaprticles was 1/1. The loading contents of DOX and CXB were 3.92% and 7.98%, respectively
