green synthesis of silver nanoparticles using salix aegyptiaca and its application in traditional medicine

the nanotechnology and biomedical sciences opens the possibility for a wide variety of biological research topics and medical uses. green synthesis and characterizations of nanoparticles has become an important branch of nanotechnology. in this paper, we report green synthesis of silver nanoparticles (agnps) using the extract of salix aegyptiaca as a reducing and stabilizing agent. this approach is a simple, cost-effective and stable for a long time, reproducible in room temperature and an eco-friendly manner to obtain a self-assembly of agnps. the resulting nanoparticles are characterized using uv-vis, tem, xrd and ft-ir spectroscopic techniques. in traditional medicine of iran, with adding salix aegyptiaca extract to pure silver, they obtained a brown powder is called "kushta nuqra". after processing the salix aegyptiaca extract using silver, a drug with palpitation, weakness of the heart, cerebral atony, liver dysfunction, anxiety, sexual debility, spermatorrhoea, nocturnal emission and hydrospermia properties can be formulated.
