METHOD FOR MANUFACTURING GOLD NANOPARTICLES WITH CHANGED SHAPES CAPABLE OF BEING USED FOR A CATALYST, A BIO SENSOR, A CELL IMAGING ELEMENT, AND A PHOTOELECTRIC ELEMENT

摘要

PURPOSE: A method for manufacturing gold nanoparticles is provided to obtain the gold nanoparticles with various shapes by controlling the amount or the reaction time of a reaction regulator.;CONSTITUTION: A method for manufacturing gold nanoparticles forms a reaction solution by dissolving gold salt, a dispersing stabilizer, and a reaction controller. The reaction solution is heated. The reaction controller controls the concentration of salt ions in a reaction process. The generation of multiply twinned particles based on the gold nano particles is suppressed. The gold salt is one or more selected from a group including HAuCl_4, AuCl, AuCl_3, Au_4Cl_8, KAuCl_4, NaAuCl_4, NaAuBr_4, AuBr_3, AuBr, AuF_3, AuF_5, AuI, AuI_3, KAu(CN)_2, Au_2O_3, Au_2S, Au_2S_3, AuSe, Au_2Se_3, and AuTe_2.;COPYRIGHT KIPO 2011
