The characters of CMCS-hyd-CUR-EGFR-mAb were identified. The in vitro release studies revealed that this drug delivery system was acid-sensitive, and the self-assembled nanoparticles which were spherical. The in vitro results indicated that the dual-receptor targeting nanoparticles could be faster internalized into the Cal-27 cells via receptor-mediated endocytosis, which exhibited better antitumor activity than the one-receptor nanoparticles. The experimental results clearly reveal that CMCS-hyd-CUR-EGFR mAb provides a novel way for drug delivery in oral cancer treatment.展开更多
