▎ 摘 要
NOVELTY - The method for synthesizing graphene oxide nanosilver involves mixing natural graphite with sulfuric acid, potassium permanganate and sodium nitrate to obtain graphite oxide, and mixing graphite oxide with silver nitrate and quercetin to obtain graphene oxide nanosilver composite material. USE - The method is useful for synthesizing graphene oxide nanosilver, which is useful as anti-tumor substitute drug. ADVANTAGE - The method can synthesize the graphene oxide nanosilver in a simple manner. The synthesized graphene oxide nanosilver overcomes the drug resistance of tumors.
