▎ 摘　　要

NOVELTY - Near-infrared light-responsive photosensitizer complex comprises graphene quantum dot and a photosensitizer loaded on the graphene quantum dot. USE - The photosensitizer complex is useful in preparing near-infrared photodynamic therapy medicine for treating tumor (claimed). ADVANTAGE - The photosensitizer complex has good biological compatibility, is good for promoting the treating effect of tumor photodynamic therapy, and is helpful for further pushing the graphene quantum dot application and development in the field of biomedicine. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing near-infrared light response photosensitizer complex comprising dropwise adding photosensitizer solution into the graphene quantum dot solution to react, filtering the mixed solution after reaction, removing precipitate, obtaining the near-infrared light response photosensitizer complex.
