  Green synthesis is a novel approach for the biogenesis of nano-particles- tiny structures having enormous applications. In the current study, fungal strains were explored for their ability to biosynthesize both intra- and extracellular gold nano-particles. Out of twelve, four fungal strains namely SSG-2, SSG-5, SSG-8 and SSG-11 were selected on the basis of development of varied colors in cell free supernatant and fungal beads upon exposure with tetra-chloroauric acid. Crystallographic characterization of biomass associated, and cell free nano-particles were carried out by X-Ray Diffraction (XRD) and UV-Visible spectroscopy. A wide variation in crystallite size for intracellular and extracellular nano-particles has been observed. Further these intra- and extracellular nano-particles exhibited intense antimicrobial activities against human pathogens.
