Abstract: Biosynthesis of nanoparticles is under exploration is due to wide biomedical applications and research interest in nanotechnology. Bioreduction of silver nitrate (AgNO3) used for the synthesis of silver nanoparticles respectively with the plant extract, Pelargonium graveolens leaf oil crude extract. The plant extract is mixed with AgNO3, incubated and studied synthesis of nanoparticles using UV–Vis spectroscopy. The nanoparticles were characterized by X-ray diffraction (XRD), FTIR, TEM and SEM equipped with EDS. The silver nanoparticles synthesized were generally found to be spherical in shape, while some of the NPs were found to be having structures of irregular shape with diameter of 164 nm and 122 nm. The results showed that the Pelargonium graveolens leaf oil extract is very good bio reductant for the synthesis of silver nanoparticles and synthesized nanoparticles active against clinically isolated human pathogens against Candida albicans, Candida tropicalis and Candida kefyr.
