Among the most important advantages of the proposed method, is its simplicity, high speed, independency on expensive devices and biocompatibility.

Silver nanoparticles have special physical and chemical properties and biological activity. After many researches, the application of silver nanoparticles has widely increased, specially in health and hygiene fields. For instance, covering of the wounds, surgery devices and bone prostheses are coated with silver nanoparticles. Therefore, numerous methods have been invented for the production of the nanoparticles, such as chemical and physical deposition, reverse missile, hydrothermal and chemical vapor deposition. Among the present methods, nanophyto synthesis is a green method that has many advantages over other normal methods.

In this research, silver nanoparticles were synthesized through nanophyto synthesis method from the extract of viburnum lantana leaves. The proposed method is fast, simple and biocompatible and does not create any environmental pollution or hazard. The production of these nanoparticles through the proposed method is also cost-effective.

According to the researchers, the produced silver nanoparticles are cubic with average dimension of 48 nm. Studies showed that the antibacterial activity of silver nanoparticles with the cubic shape has a greater effect on microorganisms and cells than those with spherical shape.

Results of the research have been published in Synthesis and Reactivity in Inorganic Metal-Organic and Nano-Metal Chemistry, vol. 45, issue 3, 2015, pp. 381-387.
