Abstract

Low accumulation of chemotherapeutic agent in tumor tissue and multidrug resistance (MDR) present a major obstacle to curing cancer treatment. Therefore, how to combine several therapeutics in one system is a key issue to overcome the problem. Here, we demonstrate epidermal growth factor receptor (EGFR) antibody-conjugated PEGylated nanographene oxide (PEG-NGO) to carry epirubicin (EPI) for tumor targeting and triple-therapeutics (growth signal blocking, chemotherapy, photothermal therapy) in tumor treatment. This synergistic targeted treatment simultaneously enhances the local drug concentration (6.3-fold) and performs the ultra-efficient tumor suppression to significantly prolong the mice survival (over the course of 50 days).
