Abstract
Analysis of the feasibility of the biosynthesized nanoparticales and core-shell alloy nanoparticales from fungal strains is particularly significant. In this study, the synthesis of silver particles using fifteen isolates of Aspergillus niger were isolated from soil, where strain KSU-12 is only one was produced silver nanoparticales. Predominantly monodispersed and spherical silver nanoparticles (AgNPs) in the size range of 5-35 nm upon addition of 1 mM silver nitrate. The AgNPs were characterized by determining the time dependent increase in surface plasmon resonance (SPR) through UV-Vis spectrophotometery, Fourier transform infrared spectroscopy (FTIR), Energy Dispersive Spectroscopy (EDS), transmission electron microscopy (TEM) and scanning electron microscopy (SEM).
