The Pomegranate, punica granatum belongs to the family lythraceae is an ancient fruit. The present study has attempted to analyze the work done by different researchers on green synthesis of silver nanoparticles and their characterization by different techniques like UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Tunnling electron microscopy (TEM) and X-ray diffraction method (XRD). The antimicrobial activity were also analyzed in the present paper.
Nanotechnology is making an impact in all spheres of human life and it is developing day by day . Nanotechnology is the application of science to control matter at nanoscale level . This field is creating a lot of excitement in biotechnology and biomedical devices . Besides these nanoparticles are playing important role in drug delivery, diagnostics imaging cancer detection, sensing, artificial implants, tissue engineering, HIV inhibition and water filtration .
Metallic nanoparticles are mostly prepared from nobel metals such as Gold, Silver, Platinum and Lead. Among the nobel metals, silver (Ag) is the metal of choice in the field of biological systems, living organisms and medicine . In nanotechnology, silver nanoparticles are the most prominent one due to its applications.
Generally, silver does not adversely affect viable cells and does not easily provoke microbial resistance. Hence silver containing materials were also employed in textile fabrics, as food additives, and in package and plastics to eliminate microorganisms. Because of such a wide range of applications, numerous methods concerning the fabrication of silver nanoparticles, as well as various silver-based compounds containing ionic silver (Ag+) or metallic silver (Ag) have been developed .

The green synthesis of silver nanoparticles by the pomegranate helped out in avoiding the use of hazardous solvents and formation of waste product. It is simple and rapid method as compare to another mode of synthesis of nanoparticles. Fruit extract both act as a reducing as well as stabilizing agent. The UV-visible, FTIR, SEM, TEM and XRD characterization confirmed the formation of spherical nanoparticles in the size range 5-40 nm and face centred cubic lattice of AgNPS. Silver nanoparticles synthesized by pomegranate extract also showed good antimicrobial activity. This antimicrobial activity is one of the major role of silver nanoparticles as a antimicrobial agent and such nanoparticles synthesized by using palnts have been various applications for human benefit.
