Analysis of colloidal nanostructures synthesized through complex route

Abstract

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. Which is new, easily reproducible, and simple to accomplish. 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 sterical orientations. Similarly, ribbon-like nanostructures are showing analogous UV–vis peaks like nanorods but their structure seems to disrupted and shaped like a ribbon. Moreover, since these nanoparticles are comprised of twisted and sharp edges, it could be helpful in many applications associated with such complex building blocks.
