Abstract
Development of biologically stimulated experimental processes for the biosynthesis of nanoparticles is an essential branch of nanobiotechnology. Biocompatible silver nanoparticles have acknowledged significant notice in recent years because of their capable applications in bioimaging, biosensors, biolabels, and biomedicine. This study reports a green chemistry approach for the biological synthesis of silver nanoparticles by using the rhizomes extract of Dioscorea Pentaphylla. The properties of synthesis nanoparticles were characterized by UV-Visible spectroscopy, FT-IR, SEM, TEM and EDS. Surface Plasmon Resonance (SPR)
 spectrum for silver nano-particles is obtained at 426 with dark brown color. FT-IR spectroscopy revealed that silver nanoparticles were functionalized with bio- molecules that have primary amine group (NH2), carbonyl phenolic group (-OH) and other stabilizing functional groups. The Morphological studies revealed that the particles are spherical in shape and in the size ranged from 20 ± 1nm. The effects of silver nanoparticles concentration and extract concentration were investigated and DPR-AgNPs showed the better pharma- cological applications.
