Evaluation of the Efficiency of Tallens, Polysaccharides and microbial Methods in Synthesis of Silver Nanoparticles

One of the important aspects of nanotechnology application is expanding sustainable and eco-friendly procedures for synthesis of metallic nanoparticles. Therefore, the green synthesis methods become customary for synthesis of nanoparticles. In this research, green polysaccharide methods, modified polysaccharide, tollens and microbial methods were investigated. In polysaccharide and tollens methods, starch and β-D glucose were used as a satabilizer and reducer respectively. In biological method biomass and cell filtrate of the Fusarium oxysporum fungus were used for synthesis of nanoparticles. SEM images and UV-visible absorbtion spectra of these procedures showed that the polysaccharide method produced smaller silver nanoparticles (20 nm), more resistance (2 months) and higher efficiency. Also, TEM imageindicated that the shapes of these particles are spherical.
