چکیده انگلیسی

Three endophytic fungi Aspergillus tamarii PFL2, Aspergillus niger PFR6 and Penicllium ochrochloron PFR8 isolated from an ethno-medicinal plant Potentilla fulgens L. were used for the biosynthesis of silver nanoparticles. Scanning and transmission electron microscopic analysis were performed to study the structural morphology of the biosynthesized silver nanoparticles. The electron microscopy study revealed the formation of spherical nanosized silver particles with different sizes. The nanoparticles synthesized using the fungus A. tamarii PFL2 was found to have the smallest average particle size (3.5 ± 3 nm) as compared to the nanoparticles biosynthesized using other two fungi A. niger PFR6 and P. ochrochloron PFR8 which produced average particle sizes of 8.7 ± 6 nm and 7.7 ± 4.3 nm, respectively. The energy dispersive X-ray spectroscopy (EDS) technique in conjunction with scanning electron microscopy was used for the elemental analysis of the nanoparticles. The selected area diffraction pattern recorded from single particle in the aggregates of nanoparticles revealed that the silver particles are crystalline in nature.
