Special antitumor immune effects of laser immunotherapy with SWNT-GC

In our previous work, we constructed a multifunction nano system SWNT-GC, which can synergize photothermal and immunological effects. To further improve the application of this system, we study the cytotoxicity of SWNT-GC and investigate the effects on malignant tumor therapy. Here, we selected the optimal concentration of GC and SWNTs for the stable SWNT-GC construction. No cytotoxicity was observed under the dose used in the experiments. Using mouse melanoma tumor model, Laser+SWNT-GC treatment resulted in a significant mice survival rate, there were no long-term survivors under other treatment. It is providing a promising treatment modality for the malignancy.
