NOVELTY - Preparing gold nanorod/graphene oxide composite material involves weighing proper amount of graphene oxide and carrying out grinding. The 0.1-2mg obtained graphene oxide and 0.1g sodium polystyrene sulfonate polymer solution are mixed and subjected to ultrasonic reaction with power of 500-1000W for 30 minutes, and then centrifuged to obtain clean liquid. The obtained clean liquid is re-dispersed in proper amount of water. USE - Method for preparing gold nanorod/graphene oxide composite material (claimed). ADVANTAGE - The method enables to prepare gold nanorod/graphene oxide composite material, which has mild reaction condition, simple operation, short time, strong repeatability, implements diagnosis and treatment efficiency and has wide prospect for embellished antibody and loaded-drug. DETAILED DESCRIPTION - Preparing gold nanorod/graphene oxide composite material involves weighing proper amount of graphene oxide and carrying out grinding. The 0.1-2mg obtained graphene oxide and 0.1g sodium polystyrene sulfonate polymer solution are mixed and subjected to ultrasonic reaction with power of 500-1000W for 30 minutes, and then centrifuged to obtain clean liquid. The obtained clean liquid is re-dispersed in proper amount of water. The 5mL of 2M hexadecyltrimethylammonium bromide solution, 625 mu L of 0.008M chloroauric acid solution, 3.975mL deionized water, graphene oxide solution product, 300 mu L of 0.004M silver nitrate, 12 mu L concentrated hydrochloric acid, 75 mu Lof 85.8mM ascorbic acid, and 7.5 mu L of 0.01M sodiumm borohydride solution are mixed for 30 seconds, and shaken at 25-30 degrees C for 4-24 hours to obtain shaken material. The obtained shaken material is subjected to centrifugation at speed of 14000 revolutions per minute for 20 minutes. The pellet is re-dispersed in water to obtain final product.
