Aspect-ratio-controlled Au Nanorods: Preparation and Dispersion toward Applications

  • Yoshiko Takenaka


The synthesis of aspect-ratio-controlled gold nanorods is introduced. Gold nanorods are usually synthesized in a liquid-state surfactant solution. In this paper, we present that their synthesis in a gel-state surfactant solution is useful to control their diameter and length in wide range. The diameter is controlled from ~10 to 80 nm. According to the previous study, it is reported that a decrease in the curvature of the surfactant bilayer neighboring the gold surface affects the increase in the nanorod diameter. In this paper, we synthesize the nanorods with different kinds of surfactants and confirm that the mechanism is appropriate. We also introduce a method to control the long-axis length of gold nanorods in a gel-state surfactant solution from several tens of nm to 1 μm. The dispersion method of high-aspect-ratio gold nanorods is also presented.
