Abstract-Anisotropic metallic Nanoparticles (NPs) have unique optical properties, such as Surface Enhanced Raman Scattering （SERS）spectrosco py. In this paper, star-shaped and sphere gold NPs were prepared by seed-media ted growth and Frence methods respectively. The reaction process and the effect of reagent in seed-mediated growth of gold nanostar particles were systematical ly described. After fabricating NPs the authors test their Raman enhancement usi ng Crystal Violet (CV) molecules apart. The experimental results indicated that star-shaped Au NPs had stronger Raman enhancement spectrum than that of sphere Au NPs.
