Patent US8956440B2. issued 2015-02-17. Retrieved from https://hdl.handle.net/1911/80175.https://hdl.handle.net/1911/80175The present invention provides improved methods for preparing cetyltrimethylammonium bromide-capped gold nanoparticles through the use of hydroquinone as a reducing agent. Such methods generally comprise the steps of: (1) providing a seed solution comprising a gold nanoparticle; (2) providing an aqueous growth solution comprising: (i) cetyltrimethylammonium bromide, (ii) hydrogen tetrachloroaurate, and (iii) hydroquinone; and (3) adding a quantity of the seed solution to the aqueous growth solution.14 ppengUtility patentUS8956440B2
