Application of graphene quantum dots for drug delivery of anticancer

Cancer is one of the causes of human mortality which has become a public danger all over the world. The primary strategies for healing and treating cancer include surgery, radiation and chemotherapy. The primary treatment in a cancer clinic is usually chemotherapy. However, the effectiveness of chemotherapy is often limited by its side effects. For example, the toxicity of bleeding and cardiac toxicity, as chemotherapeutic agents, can not only break down cancer cells, but also damage healthy cells and tissues in the body [1]. Nanotechnology appears as a promising tool for reducing side effects and effective treatment for cancer chemotherapy. Among the various candidates for nano chemotherapy agents, graphene quantum dots appear to be a striking issue for extensive research. The highlight of this single-atomic layer is with very small horizontal dimensions and oxygen-rich functional groups at the edges. Another feature of graphene quantum dots is their fluorescence origin, graphene quantum dots because of the quantum amplitude and edge effects are the ideal platform for delivering chemicals to cancer cells without using additional fluorescence markers [2-4 ].
