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 HAuCl 4 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.
