Abstract:

Nanotechnology is getting an incredible drive due to the potential of manipulating metals into their nano size particles. The synthesis and characterization of nano particles using green technology have many applications. The wet chemical techniques used presently in the synthesis of nano particles are deleterious along with flammable conditions. Silver nanoparticles have the capability of killing microbes in an effective manner. This paper explains about the green technology and pollution free methodology for synthesizing silver particles at nano scale using 1mM silver nitrate solution from the extracts of Carica papaya, Emblica officianalis, Azadirachta indica and Cocos nucifera. When the silver nanoparticles are synthesized the solution turns to brownish yellow colour. The tools used in the characterisation of silver nano particles are Ultra Violet - Visible absorption Spectroscopy and Field Emission Scanning Electron Microscopy. The solutions with silver nanoparticles showed the maximum absorption at 450 nm with Ultra Violet - Visible spectroscopy. It is found that C. Papaya and E. oficianalis showed the maximum absorbance of 0.578 and 0.59 respectively at 450 nm. The average range of the produced silver nano particles are analysed to be 5 – 70 nm with FESEM and the shape is examined to be spherical.
