The synthesis of nanoparticles from biological processes is evolving a new era of research interests in nanotechnology (1-2). In this project, we aimed to develop a rapid ecofriendly method for the synthesis of silver nanoparticles using aqueous extract of Umbilicaria Americana. The synthesized nanoparticles were characterized using UV-Vis spectroscopy, FT-IR, x-ray diffraction (XRD), scanning electron microscopy (SEM). UV-vis spectroscopy derived spectrum demonstrated a peak of 420 nm which corresponds to the absorbance of silver nanoparticles. The results revealed that the aqueous extract of U. Americana is a clean, nontoxic and ecologically sound manner and very good bioreductant for the synthesis of silver nanoparticles.
