Abstract
The synthesis of silver nanoparticles is an expanding research area due to the potential applications for the development of novel technologies. In this work, a cost effective and environment friendly technique for green synthesis of silver nanoparticles were carried out from 3mM silver nitrate solution through the extract of Enteromorpha linza (L.) J.Ag. as reducing as well as capping agent. In the process of synthesizing silver nanoparticles, a rapid reduction of silver ions was observed leading to the formation of stable crystalline silver nanoparticles in the solution. The synthesis of silver nanoparticles was prepared by adding silver nitrate solution (3mM) to the plant extract. The formation of silver nanoparticles was characterized using colour change, UV-Visible Spectroscopy, FT-IR and X-Ray Diffraction Method (XRD). The nanoparticles showed an absorbance at 426nm on UV-Vis spectroscopy. The presence of proteins was identified by Fourier Transform Infra-Red spectroscopy (FT-IR). The presence of elemental silver was characterized by X-Ray Diffraction Method (XRD). The results recorded from the above techniques are support the green synthesis and characterization of silver nanoparticles.
