Flower Shaped Gold Nanoparticles: Biogenic Synthesis Strategies and Characterization.

ABSTRACT: Microbes can serve as mediators for the fabrication of complicated nano-structures, obviating the tedious and time-consuming methods of synthesis. The shape of a nanoparticle has a very prominent role in defining the functionality in prospective arenas. So, the flower shaped nanoparticles are in focus nowadays due to their enhanced electrocatalytic and optical properties as compared to the spherical ones. We present the biosynthesis of flower shaped gold nanoparticles by Bacillus subtilis RSB64 and process parameters optimization using central composite design. The two well-separated scattering spectra showing absorption peaks at 540 nm and 750 nm indicate the presence of anisotropic gold nanoparticles and the results were corroborated by transmission electron microscopy analysis.
