Formation of Silver Nanoparticles in the root extract of Scutellaria baicalensis and their characterization

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.
