Preparation of Anisotropic Gold Particles Using a Gemini Surfactant Template.
Anisotropic gold particles were prepared in a gemini cationic surfactant solution by reduction of HAuCl4 with UV irradiation. With increasing concentrations of both HAuCl4 and the surfactant, fibrous gold particles were obtained and their length increased. These results suggest that the gemini surfactant which provides threadlike micelles operates as a soft template for anisotropic gold particles. Copyright 1998 Academic Press.
