Nanobiotechnology has emerged as a promising technology to develop new therapeutically active nanomaterials. To avoid the chemical toxicity, biosynthesis (green synthesis) of metal nanoparticles is proposed as a cost-effective and environmental friendly alternative. seed extract of Moringa oleifera is a medicinal agent in this work to prepare silver nanoparticle. From XRD it was found that sample posssess Face Centered Cubic structure and has crystalline size of 22.08 nm. FTIR results proved that the components in Moringa oleifera seeds act as good reductants and stabilizers for the silver nanoparticles.The absorption in the visible region and broad peak at 480 nm was studied by UV studies. The antibacterial activity of bio-synthesized silver nanoparticles were analyzed against E.coli, Klebsiella, Pseudomonous, Staphylococcus bacteria. The results revealed that the seed extract is an excellent bioreductant for the synthesis of silver nanoparticles.
