“…Distinguish from the conventional cancer treatment (e.g., surgery, radiotherapy and chemotherapy), noncellular immunotherapy such as checkpoint inhibitors (e.g., PD-1, PD-L1, CTLA4), lymphocyte-promoting cytokines (e.g., IFN-γ, GM-CSF, G-CSF), and cancer vaccines (e.g., mRNAs) has been continuously developed to fulfill the goals for cancer administration as well [14][15][16][17]. Additionally, current progress has also highlighted the feasibility of nanomaterials (e.g., organic nanomaterials, inorganic nanomaterials, organic-inorganic hybrid nanomaterials) as promising agents for cancer therapy based on the knowledge of nanobiotechnology and clinical biomedicine [18][19][20]. However, the significant disadvantages of the aforementioned strategies are apparent and should not be ignored including drug delivery barriers, graft-versushost disease, off-target effects and severe toxicity [5,21,22].…”
