In vitro Synthesis, Characterization and Medical Application of Silver Nanoparticle by Using a Lower Fungi
2014
2 Abstract: Nanotechnology is a rapidly growing science of producing and utilizing nano sized particles that measure in nanometers. In this study we have reported the biological synthesis of silver nanoparticles using Aspergillus niger and its antimicrobial properties. The extracellular mechanism of silver nanoparticle creation was investigated by UV-VIS spectroscopy, FTIR spectroscopy. The mechanism leading to nanoparticle formation was studied using nitrate reductase assay. The particles were further characterized using SEM with EDS, Particle size analysis. Obtained silver nanoparticles when tested for the antimicrobial action showed good results against the Gram positive and Gram negative bacteria.
