The synthesis of nanoparticles has become a matter of great interest in recent times due to their various advantageous properties and applications in a variety of fields. Recently, the exploitation of different plant materials for the biosynthesis of nanoparticles is considered a green technology because it does not involve any harmful chemicals. Among them, Iron nanoparticles (Fe NPs) are gaining importance for their use in environmental remediation technologies. In the present study, iron oxide nanoparticles (Fe₃O₄-NPs) were synthesized using a rapid, single step and completely green biosynthetic method by reduction of ferric chloride solution with Wrightia tinctoria leaf extract which acts as reducing agent and efficient stabilizer at room temperature. Synthesized nanoparticles were characterized using UV-visible spectrophotometer FT-IR, X-ray diffraction and SEM methods. The morphology of the nanoparticles mostly appeared to be porous and spongy, nanoclusters with panoramic view and range from 105-145 nm in size. X-ray diffraction showed that the nanoparticles are crystalline in nature, with a cubic shape and rhombohedral geometry. The synthesized Iron oxide nanoparticles exhibited potent antibacterial activity against gram positive and moderate activity against gram negative bacterial strains tested.  Novelty of this present study is that the plant extract is very cost effective and eco friendly and thus can be economic and effective alternative for the large scale synthesis of iron oxide nanoparticles.
