Tumor microenvironment is characterized by low pH, high reactive oxygen species and hypoxia, whichprovides a suitable environment for cancer growth. The hypoxia not only elevates tumor angiogenesisand metastasis, but also is responsible for the development of treatment resistance, which graduallybecomes a significant impediment for cancer therapy. Therefore, we developed a biomimetic nanosystemcontaining hemoglobin extracted from red blood cells, chemotherapy drug sorafenib, sensitizer ursolicacid and photosensitizer indocyanine green for enhanced chemo-photo combination therapy of hepatocellularcarcinoma, which could not only enhance the chemotherapy effect of sorafenib bowing to thesensitizing effect of ursolic acid, but also achieved synergetic phototherapy in virtue of indocyaninegreen. Besides, the nanoparticles could effectively delivery exogenous oxygen to tumor site and amelioratethe tumor hypoxic environment with the assistance of hemoglobin. The dual-sensitization drugdelivery system was expected to effectively reduce the resistance of traditional treatment methodsagainst tumor hypoxia, providing a novel prospect for the synergistic hepatocellular carcinomatreatment.
