Abstract:

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.

Antiviral properties of silver nanoparticles synthesized by Aspergillus sps

An invitro study was conducted to investigate the antiviral properties of silver nanoparticles synthesized from fungal strain Aspergillus sps isolated from soil. The isolated and characterized silver nanoparticles exhibited as an excellent antiviral property on Bacteriophage viral strain. The viral inactivation process was increased with increasing the concentration of silver nanoparticles.
