Higher research and development of silver nanoparticles (AgNPs) is great due to their use full applicationsin present time silver nanoparticles were successfully synthesized by using carica papaya root extract. In the present time the aim of the biosynthesis of silver oxide nanoparticle to making a new drug. Temperature and extract concentration were found to control the size and shape of the biosynthesized silver nanoparticles The synthesized AgNPs were characterized by UV–visible spectroscopy, scanning electron microscopy (SEM), Morphological images of prepared  nanomaterials exposed that the particles are in spherical shape and size ranging between 10 and 100 nm. The mode of action of AgNPs on the bacteria was studied against isolated bacterial pathogens, Staphylococcus aureus, Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa using confocal and electron microscopy, Crystalline nature of nanoparticles in face centered cubic (fcc) structure was ensured by diffraction pattern peaks corresponding to (1 1 1), (2 0 0), (2 2 0) and (3 1 1) planes spectroscopy analyses indicates that nanoparticles

Key words: Biosynthesis of silver oxide nanoparticle , UV- VIS, SEM. Anti bacterial activity, Carica papaya root
