In this study, different nanoparticle formulations of doxorubicin anticancer drugs were prepared. The efficacy of the formulations produced in the cell culture medium was studied compared with the free drug.Methods: Reverse phase evaporation was used to form the liposome containing doxorubicin. The graphite nanoparticles were prepared. These nanoparticles were mixed with the liposome containing doxorubicin, and the related Nano-complex was conjugated. Spectroscopy methods for visible light-ultraviolet light and light dynamics differentiation were used to describe nanoparticles. For toxicity of different formulation, MTT and 7-MCF cells were used.Results: The amount of drug loading in the liposomes was 72%. The largest amount was related to the Nano-conjugated complex and the smallest size was related to the graphene-oxide nanoparticle with a nanometer size. The controlled release in 96 hours and the amount of drug release was 95.43%. Doxorubicin-containing liposome toxicity was 75% and Nano- conjugated complex was 85%, at the lowest drug concentration (10 micromolar). The free drug created 35% cell toxicity in 10 micromolar and 89% in 2500 micromolar.Conclusion: The results of the study showed Liposomes act as a suitable nanoparticle for doxorubicin. It was found that the effect of nanoparticles of graphene oxide is very important. In the presence of this nanoparticle in the complex, toxicity increased significantly.
