METHOD OF PRODUCING GOLD NANOPARTICLES IN COLLOIDAL SOLUTIONS IN PRESENCE OF AMINO ACIDS

摘要

A method for producing gold nanoparticles in colloidal solutions in the presence of amino acids comprising a stage of forming a gold colloidal solution by chemical synthesis at recovery of gold compounds up to metallic gold. Amino acid is added directly during the process of formation of the colloidal solution by chemical synthesis. At the same time sodium borohydride NaBHand/or a mixture of ascorbic acid and sodium hydroxide is used as a reducing agent.
