Extracellular biosynthesis of gold nanoparticles using a gram negative bacterium Pseudomonas fluorescens
Journal Title: Asian Pacific Journal of Tropical Disease - Year 2012, Vol 2, Issue 0
Abstract
Objective: In the present study, the extracellular synthesis of gold nanoparticles were made by making use of Pseudomonas fluorescens. Methods: The nanoparticles obtained were characterized by UV –vis, transmission electron microscopy (TEM), Scanning electron microscopy (SEM) and FTIR spectroscopy. Results: Synthesized nanoparticle size ranged from 50-70 nm. FTIR spectrum indicates that the biomolecule cap the nanoparticles. Conclusions: Hence the present study enlightens the green chemistry approach on the production of gold nanoparticles using a microorganism. In comparison to chemical synthesis, the synthesis of gold nanoparticles by microbial source is the most reliable method of production and yield.
