Paper Title:
Synthesis of Gold Nanodogbones by the Seed Mediated Growth Method with Addition of Vitamin C Solvent
  Abstract

A simple seeded mediated growth (SMG) method with addition of vitamin C solvent to prepare novel gold nanodogbones is reported. In SMG method, gold nanodogbones are produced in reasonable yield by chemical reducing HAuCl4 in surfactant solution, with small seed gold particles added as nucleation centers for the preparation of large size nanoparticles. Besides, the surfactant absorbs strongly (as a bilayer) along the crystal face of the nanoparticle. The surfactant is usually considered to be a soft micelle-template, which controls the size and shape of the nanoparticles. In this study, the role of vitamin C is found to alter gold nanoparticles shape from rod structures to dogbone-like structures. The aspect ratio of gold nanodogbones can be easily controlled by addition amount of vitamin C solvent from 10 to 30 µL.
