Abstract:
Nanoparticles have attracted considerable interest because of their unique optical, electromagnetic and catalytic properties that differ from bulk ones. The origin of these properties is their large surface to volume ratio and from the coherent oscillation of the conduction electrons that can be induced by interactive electromagnetic fields. Since these electromagnetic properties vary with the size and shape of the novel metal particles, the focus of many studies has been on methods for controlling the size and shape of gold Nanoparticles. The aim of this work has been to deliver the effect of various reducing agents on size and shapes of gold Nanoparticles formed. The morphology of gold Nanoparticles along with their size and shape has been outlined in this paper. Gold Nanoparticles formed by hydrazine sulphate as a reducing agent have branched or the so-called sea urchin shape resembling to the shape that of familiar sea animal. This shape was synthesized for the first time and may find applications in various biomedical or related fields
