Formation of Silver Nanoparticles in the root extract of Scutellaria baicalensis and their characterization
Journal Title: Archives of Nanomedicine: Open Access Journal - Year 2018, Vol 1, Issue 5
Abstract
This research about on the formation of silver nanoparticles (AgNPs) in extract of Scutellaria Baicalensis roots. Comprehensive analyzes were carried out and the characteristics of these nanoparticles, which can be used in medical practices and environmental cleaning problems. The roots extracts of Scutellaria Baicalensis advocates as reductant and stabilizer. The first proof of the formation of AgNPs is the change of color of solution AgNO3 which was added root extract. Then by UV-Vis spectroscopy identificated the absorption peak of AgNPs at 414nm –461nm interval. Other characterization of AgNPs received with SEM analysis, From SEM pictures it is clear that the AgNPs have a spherical form, with size ranging from 7.12nm to 18.8nm. An average size of AgNPs are 11.35nm. By FTIR analysis of AgNPs was established the structures, the respective bands of the synthesized nanoparticles, and the stretch of bonds. Last years, scientists have tried to create different methods and technologies to get non-toxic forms of nanoparticles. A chemical synthesis of nanoparticles, especially precious metals is widespread. However, since nanoparticles obtained in this way are expensive and toxic, their synthesis in biological methods is of great interest recently. In biosynthesis of nanoparticles no needs applied high pressure and energy, temperature and toxic chemicals. The possible ecofriendly alternatives to chemical and physical methods are biological methods synthesis of nanoparticle using microorganisms [1-3] enzymes [4], fungus [5], and plants or plant extracts [6-8]. Biological synthesis of nanoparticles using plants extracts in many cases is advantageous than other biological methods which may eliminating the elaborate processes in the technological point of view [9]. The application of nanotechnology in medicine has put this issue more seriously. In this regard, silver nanoparticles having a unique optical and mechanical properties, having antiseptic properties, are of particular importance.
