▎ 摘 要
NOVELTY - Preparing graphene-gold nano composite material comprises (a) adjusting the pH value of the chloroauric acid solution to 10.5-11.5 to obtain alkaline chloroauric acid solution, and (b) taking the obtained alkaline chloroauric acid solution and nano-gold particles, hydroxylamine hydrochloride solution and graphene oxide for reduction reaction. USE - The method is useful for preparing graphene-gold nano composite material. ADVANTAGE - The material has photo-thermal converting property and can kill tumor cells by heat treatment.
