The use of silver nanoparticles in the field of nanomedicine is keeping pace and innovating with the ever expanding horizon of Nanobiotechnology. Ipomea species is widely cultivated and use for different purposes, such as, nutritional, medicinal, ritual and agricultural. The present study deals with the synthesis and characterization of silver nanoparticles using methonolic extract of Ipomoea indica flowers. UV-visible spectroscopy studies were carried out to assess the formation silver nanoparticles. The formation of Ag-NPs was confirmed by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) studies. SEM image revealed that silver nanoparticles are quite polydispersed, the size ranging from 10nm to 50nm. The formation of crystalline silver nanoparticles was zconfirmed using X-ray diffraction analysis. Extracellular synthesis of Ag nanoparticles using dried biomass appears to be cost effective, eco-friendly to that of conventional methods of nanoparticles synthesis.
