▎ 摘　　要

NOVELTY - Use of graphene oxide is claimed for preparing agent for promoting dendritic cell function, preferably maturity and/or migration ability of dendritic cells. USE - The graphene oxide is useful for preparing agent for promoting dendritic cell function, preferably maturity and/or migration ability of dendritic cells (claimed). ADVANTAGE - The graphene oxide has stable structure and relatively simple composition and is cost-effective, easily available and more conducive to clinical transformation in dendritic cell vaccine preparation.
