Nanotechnology have emerged a new technology in nanomedicine applications to produce alternative medicines which can counter the antibiotic resistance to be implemented in healthcare area. The present study focus on to synthesize silver nanoparticles by the using the plant Nepenthes. sp. The synthesis of nanoparticles was observed by the change in the color of extract in to dark brown. Characterization of silver nanoparticles was done by UVVisible spectrophometery and Fied Emission electron microscopy (FESEM) which showed the size around 20 – 30 nm . These nanoparticles showed excellent antibacterial activity against some common bacterial pathogens.
