▎ 摘　　要

NOVELTY - A graphene oxide/bismuth selenide/polyvinylpyrrolidone composite nanomaterial is prepared by dispersing nano graphene oxide in alcohol, then adding bismuth source and selenium source, adding anhydrous sodium sulfite and polyvinylpyrrolidone, and performing solvothermal reaction for 1-2 hours at 180-220 degrees C to obtain the composite nanomaterial. USE - Method of preparing graphene oxide/bismuth selenide/polyvinylpyrrolidone composite nanomaterial used in preparing near-infrared photothermal cancer therapy reagent and computed tomography (CT) contrast agent (claimed). ADVANTAGE - The method utilizes easy to obtain raw material, has simple operation and low cost, and is suitable for industrial production. The obtained composite nanomaterial has high photothermal conversion efficiency and provides good CT imaging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene oxide/bismuth selenide/PVP composite nanomaterial.
