Green synthesis of silver nanoparticles using Ixora coccinea leaves extract

Biologically dependable processes for the green synthesis of silver nanoparticles (Ag NPs) were developed in nanoscience and nanotechnology. In this present paper, green synthesis of Ag NPs was performed from aqueous silver nitrate using the fresh Ixora coccinea L, leaves extract. The formation of Ag NPs was observed by the change of color from colorless to dark brown by the addition of silver nitrate into leaves extract. The synthesized Ag NPs were characterized by UV-vis, FTIR and XRD analyses. Further, the size and shapes of Ag NPs were identified by field emission scanning electron microscope (FESEM) technique to obtain particle sizes in the range from 13 to 57 nm. (C) 2013 Elsevier B.V.
