Evaluation of the effective factors on size and anti-bacterial properties of biosynthesized Silver nanoparticles

Developing reliable and eco-friendly processes for the synthesis of metallic nanoparticles is an essential step in the field of application of nanotechnology .Using natural factories such as biological systems is a way of developing such processes. Nowadays, the synthesis of silver nanoparticles is very common due to its numerous applications in different fields. The synthesis of these nanoparticles is carried out through physical, chemical and biological methods. However, due to its inexpensive and environmentally friendly features, the biological method is preferred to the other two methods. In the present article, the factors influencing the size of synthesized silver nanoparticles using biological methods (Which consists of living organisms such as: Plants, Fungi, Bacteria and Yeast) and the anti-bacterial properties of silver nanoparticles were investigated.
