  • Title: Biosynthesis and characterization of Au-nanostructures by metal tolerant fungi.
    Author: Gupta S, Devi S, Singh K.
    Journal: J Basic Microbiol; 2011 Dec; 51(6):601-6. PubMed ID: 21953675.
    Abstract:
    Microorganisms being eco-friendly and encompassing special features are widely employed in the biosynthesis of different metal nanoparticles (NPs). In the present study, the potential of different fungal strains has been explored for the synthesis of various morphologies of gold nanostructures. Preliminary confirmation of nanosized particles formation has been done with visual observation as the synthesized gold nanoparticles exhibited a variety of colours covering whole visible spectra. Crystallographic and morphological characterization of synthesized nano-materials associated with different fungal strains have been done using X-ray diffraction (XRD) and transmission electron microscope (TEM). Nanoparticles morphology dependence on different fungal strains has been studied and described in detail. A wide variation in shape and size of gold nanoparticles with different strains has been reported as a function of strain characteristics.
