title: Fungal mediated biosynthesis of silver nanoparticles, characterization and antimicrobial activity.
abstract: Microbial assisted biosynthesis of nanoparticles is a rapidly progressing area of nanobiotechnology. In this paper Aspergillus niger assisted extracellular synthesis of silver nanoparticles is reported. The silver nanoparticles were characterized by UV-vis spectrophotometry, TEM, EDX and FTIR. TEM studies showed the size of the silver nanoparticles to be in the range of 3-30 nm. The probable mechanism for the extracellular synthesis of silver nanoparticles by Aspergillus niger was investigated. The nanoparticles showed antimicrobial activity against fungal and bacterial strains.
