7.2　Biomedical Polymer Drug Delivery System for Immunotherapy of Melanoma

Biomedical polymer materials can play an important role in overcoming key challenges associated with immunotherapies，which can change biological distribution of drugs in the body by improving the cycles，organization homing and tissue penetration of the drugs.The synergistic effect of immunoadjuvants and immunotherapy can be enhanced through the slow release of antigen and improving the immune memory，which results in the sustainability of tumor immunotherapy（see extended reading 4）.According to their size，polymer materials used in melanoma immunotherapy can be divided into polymer nanomaterials，polymer micromaterials and macroscale polymer materials.(https://www.daowen.com)
