NOVELTY - Method for preparing nano-silver antibacterial material involves adding silver source, surfactant and graphene quantum dots to deionized water, mixing uniformly, adding reducing agent, stirring and reacting the mixture. USE - The method is useful for preparing nano-silver antibacterial material which is used for providing antibacterial effect (claimed) and treating wound infection caused by drug-resistant bacteria. ADVANTAGE - The method prepares nano-silver antibacterial material at high yield. The prepared nano-silver antibacterial material has excellent dispersibility, high biocompatibility and stability, and can continuously and slowly release small-sized silver particles.
