摘要: Here, we reported a cancer nanovaccine based on SiO 2 nanoflowers with a special radial pore structure, which greatly enhanced cross-presentation and induced the production of cytotoxic T lymphocyte cells secreting granzymes B and interferon-γ. The antigen ovalbumin was covalently conjugated onto the as-synthesized hierarchical SiO 2 nanoflowers, and the adjuvant cytosine-phosphate-guanine was electrostatically adsorbed into their radial pore by simple mixing before use. The nanovaccine exhibited excellent storage stability without …
