Abstract
To explore the immune adjuvant effect of nano mesoporous materials and laser immune effect of cancer therapy combined with chemotherapy, we designed a bionic nano tumor targeting delivery system with homologous cancer cell membrane as the outermost layer. Inorganic mesoporous silica (mSiO2) and hydroxyapatite (HAP) are used as the intermediate immune adjuvant layer and drug carrier layer, and gold nanorods(GNR) are used as the core. It degrade to release drug under the condition of low pH value, and the gold nanorods are wrapped for near-infrared laser response. Homologous cancer cell membrane wrapping is expected to greatly improve the efficiency of targeted delivery. Laser immunotherapy is more widely applied than antibody and vaccine, and has no serious side effects. Combined with controlled release drug targeted chemotherapy and encapsulated with tumor cell membrane, it is expected to further achieve low toxicity and high efficiency cancer treatment.
