However, the clinical use of miR is highly limited because of certain properties such as instability, low-specificity distribution, and metabolic toxicity. Methods: In order to improve the anti-tumor efficacy and reduce the side effects of miR in treating melanoma, a combination of graphene oxide (GO), chitosan (CS), and a cellular penetrating peptide, MPG, was prepared with solid dispersion method in this research. The research has analyzed the specific components of nano drug-loading complexes GO-CS and GO-CS-MPG through characterization research and confirmed the bio-safety of the carrier material GO-CS-MPG. Results: The GO-CS-MPG-miR33a/miR199a nano drug-loading complex was successfully constructed and its medical effectiveness was verified. Through the subcutaneous tumor implantation experiment, an evident effect of the drug-loading complex in inhibiting melanoma cells was proven. Conclusion: Results suggest that GO-CS-MPG may have potential applications in melanoma therapy. Keywords: melanoma, graphene oxide, chitosan, cellular penetrating peptide, microRNA
