چکیده

Interaction of Chrysosporium sps. and Aspergillus sps. with aqueous AgNO₃ was investigated for synthesis of silver nanoparticles. Biological reduction and extracellular synthesis of silver nanoparticles in 28 hour at 27⁰C and pH 5.6 was done. The nanometallic dispersion was characterized by surface plasmon absorbance measuring at 424 – 530 nm for Ag nanoparticles. High resolution transmission electron microscopy showed the formation of silver nanoparticles in magnification of 50-100 nm. XRD analysis of the silver nanoparticles confirmed the formation of silver nanoparticles at average size of 29.18 nm.
