Development of Biogenic Silver Nanoparticle Using Rosa Chinensis Flower Extract and Its Antibacterial Property.

In the present study, biosynthesis of silver nanoparticles was carried out using Rosa chinensis flower extract as reducing agent. The characterization of silver nanoparticles was done by UV-VIS spectrum. The morphology and size of silver nanoparticles were determined by transmission electron microscope (TEM) image. The crystallization of silver nanoparticles was confirmed by X-ray diffraction (XRD) measurements. The Fourier transform infrared (FT-IR) analysis was used to confirm the possible involvement in the formation and stabilization of synthesized silver nanoparticles by the extract of Rosa chinensis flower. Antibacterial activity of silver nanoparticles was studied against Gram positive Staphycoccus aureus and Gram negative Escherichia coil.
