PLANT MEDIATED BIOSYNTHESIS, CHARACTERIZATION AND APPLICATION OF SILVER NANOPARTICLES BY LEAVES EXTRACT OF CUPRESSUS TORULOSA.

In recent nanotechnology engineering could be a burning field for the researchers. Nanotechnology deals with the Nanoparticles having a size of 1-100 nm in one dimension used considerably regarding medical chemistry, atomic physics, and all other known fields. Nanoparticles are used vastly due to its tiny size, orientation, physical properties, that square measure reportedly shown to amendment the performance of the other material which is in touch with these little particles. These particles can be ready simply by completely different chemical, physical, and biological approaches. But the biological approach is the most rising approach of preparation, because, this method is easier than the opposite ways, eco-friendly and less time consuming. The Green rapid biogenic synthesis was demonstrated by silver nanoparticles using aqueous extracts of leaves of Cupressus torulosa D.Don leaf extract and AgNO3. Silver was of a selected interest for this technique for its sensible physical and chemical properties.Change in colour determined the formation of nanoparticles. The characteristics of the SNP’s were evaluated by UV-visible spectroscopy, Scanning Electron research (SEM), X-Ray Diffraction analysis (XRD), Transmission Electron Microscope (TEM) and therefore the bactericide activity against pathogenic bacteria Bacillus subtilis, Salmonella entrica and Pseudomonas aeruginosa of human health and study concerning the dye decolourization of the dyes Congo red, Orange G and Rhodamine B. The morphology of the particles formed consists of varied shapes such asspherical, rod, flower-like and hexagonal pattern. The biosynthesis of nanoparticles has received increasing attention because of the growing demand to supply secure, cost-effective and environmentally friendly technologies for nanomaterials synthesis.
