Silver nanoparticles synthesized using dried and aqueous Teucrium polium extract

Today, silver is produced in the form of particles smaller than 100 nm, called silver Nano particles or Nano silver. These particles exhibit unusual physicochemical property and biological activities. Through extensive research activities, the use of Nano silver, especially in the health field, has expanded vastly [1]. Silver is extensively used in Nano systems and employed in various biomedical purposes. Silver nanoparticles have excellent medical and nonmedical properties and applications when compared with other metal nanoparticles. The green approach of nanoparticles synthesis possesses reduced or no toxicity and number of plants and herbal extracts has been reported to be involved in such synthesis. Plant extracts contain number of secondary metabolite which plays a critical role during the nanoparticle synthesis by acting as reducing or capping agents. Studies have shown that silver nanoparticles are highly stable and toxic to bacteria, fungus, and viruses [2].The shapes of nanoparticles depend on their interaction with stabilizers and the inductors around them and also their preparation method. It is also known that reaction rate is influenced by the shape of synthesized silver nanoparticles [1]. In this study we prepared the aqueous extract of Teucrium polium flowers in two physical states: liquid extract and (freeze) dried extract, in the next step, after green synthesizing silver Nano particles using both types of extracts, we compared the size and the shape of both produced silver nanoparticles.
