Plant based materials and extracts have gained an increased importance for biosynthesis of metallic nanoparticles. Biosynthesis offers an economical and environmentally friendly pathway for nanoparticle synthesis. When done with plant extracts, beneficial phytochemicals get absorbed on the nanoparticles and provide functionality. In this study, we have used simple water extracts of myrtle and grape seed to facilitate the synthesis of silver nanoparticles. The nanoparticles were characterized via UV-Vis spectroscopy, XRD, SEM and Raman spectroscopy. Average size of 10-30 nm spherical particles were obtained. The antibacterial activity of the nanoparticles were tested on Gram-positive and Gram-negative model organisms. Biosynthesized nanoparticles showed superior antibacterial activity compared to conventionally synthesized nanoparticles or soluble plant extracts.
