The integration of chemotherapy and photothermal therapy into one nanoplatform has attracted much attention for synergistic tumor treatment, but the practical clinical applications were usually limited by their synergistic effects and low selectivity for disease sites. To overcome these limitations, a tumor-specific and pH/NIR dual-responsive multifunctional nanocarrier coated with mussel inspired polydopamine and further conjugated with targeting molecular hyaluronic acid (HA) was designed and fabricated for synergistic targeted chemo-photothermal therapy. The synthesized versatile nanoplatform displayed strong near-infrared absorption because of the successful formation of polydopamine coating. Furthermore, the nanosystem revealed high storage capacity for drugs and pH/NIR dual-responsive release performance, which could effectively enhance the chemo-photothermal therapy effect. With this smart design, in vitro experimental results confirmed that the drug loaded multifunctional nanoparticles could be efficiently taken up by cancer cells, and exhibited remarkable tumor cell killing efficiency and excellent photothermal properties. Meanwhile, significant tumor regression in the tumor-bearing mice model was also observed due to the combination of chemotherapy and photothermal therapy. Thus, this work indicated that the simple multifunctional nanoplatform can be applied as an efficient therapeutic agent for site-specific synergistic chemo-photothermal therapy.
