Nanostructure materials have attracted a great deal of attention because of their potential for achieving specific processes and selectivity, especially in biological and pharmaceutical applications. Of all kinds of metal nanoparticles, synthesis of silver nanoparticles is of considerable interest due to their wide range of applications in different fields. Chemical, physical and biological methods have been introduced for the synthesis of these nano particles. Offering reliable and eco-friendly processes for silver nanoparticles. Escherichia coli bacteria is one of the earliest bacteria for this purpose. Studies showed that generally the presence of nitrate reductase enzyme is essential for the biosynthesis of silver nanoparticles using bacteria. Therefore, this enzyme and its relationship with the synthesis of silver nanoparticles have been studied in the present research work. biological synthesis of metallic nanoparticles (using microorganisms) is an important step in nano biotechnology. So far, different kinds of bacteria have been reported to be used for synthesis of
