Synthesis and Characterization of Silver Nanoparticles from Fuzarium Oxysporum and Investigation of Their Antibacterial Activity
Abstract
Abstract Nanotechnology is the fastest growing field of 21st century due to this reason that the nanomaterials synthesis finds more importance in field of research. The nanomaterials can be synthesized by physical, chemical and biological methods. The biological methods are more advantageous than the other two methods because of manipulation of the size and morphology of nanostructures by microbes and plants. The Penicillium sps. Fuzarium Oxysporum was used to synthesize silver nanoparticles and the synthesis was extracellular. The nanoparticles were characterized for various studies using UV spectrophotometer, XRD, Zetasizer Nano S90, SEM, EDAX and AFM. The synthesized silver nanoparticles were found to have size in range 30-45 nm confirmed by SEM and AFM analysis. The XRD pattern confirms FCC structure of silver nanoparticles. Further, the antibacterial activity of the silver nanoparticles was tested against several antibiotics by conjugating them with antibiotics, with the help of zone of inhibition. Among several antibiotics used the efficiency of erythromycin increased by 3 fold
