Synthesis and Deposition of Irregular and Complex Gold Nanostructures

Abstract

Imtiaz Ahmad

It is a short report about the synthesis of complex shaped (sperm-like and ribbon-like) gold nanoparticles that have been achieved by using bottom up chemical synthesis technique. These methods are not only simple in approach, but it gives some new irregular shapes of gold nanoparticles. Sperm-like particle are showing some sharp edges, rounded, and twist/ turns within a single nanostructure. Instead of their irregular structure, such particles have been observed self- assembled in the best possible sterically orientations. Similarly, ribbon-like nanostructures are showing analogous UV-vis peaks like nano rods, but their structure seems to be disrupted and shaped like a ribbon. Moreover, since these nanoparticles are comprising of twisted and sharp edges could be helpful in many applications associated with such complex building blocks.
