Biosynthesis of silver nanoparticles derived Acorus Calamus rhizome extract and their biomedical application

The silver nanoparticles (Ag NPs) were derived from Acorus calamus (A. calamus) rhizome extract using different temperature. The absorbance centered at 439 nm, which was corresponds to the wavelength of the surface plasmon resonance of Ag NPs at 95 ◦C. From FESEM and TEM image showed, the Ag NPs were exhibited spherical structure. Elemental compositions were identified by EDAX analysis. The synthesized Ag NPs, functional groups were identified by the FTIR spectra. The antibacterial studies performed against a set of bacterial strains showed that the Ag NPs possessed a greater antibacterial effect than the Plant extract (PE) and silver nitrate. In-vitro cytotoxic effect of green synthesized A. calamus rhizome extract derived Ag NPs tested against MG 63, MCF-7 and HeLa cell lines
