摘要

Monodisperse carboxylate functionalized gold nanoparticles comprising a capping agent layer of pamoic acid and colloidal suspensions thereof are disclosed. These gold nanoparticles have an average particle size of greater than 15 nm or less than 8 nm and demonstrate significant fluorescent properties. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles wherein pamoic acid acts as both a reducing and capping agent and wherein the size of the particles can be controlled by the pH of the process is disclosed. In addition, a method for the size controlled preparation of these monodisperse carboxylate functionalized gold nanoparticles utilizing seed mediated growth is disclosed.
