Seeding method for three-dimensional dendritic growth of gold nanoparticles stabilized by hexatrimethylammonium bromide
Three-dimensional gold dendrites with fractal nanostructure were prepared with HAUCl(4) and I-ascorbic acid via seeding growth method in the presence of hexatrimethylammornium bromide (HTAB) as a protecting agent and architecture soft template. Spherical gold, previously generated, plays as a seed for particle growth. The surfactant HTAB helps to induce various branched nanostructures. The growth of first branches on the seeds leads to the formation of second branches by seed amount.
