Abstract The green synthesis of nano particles involving plant extract has attracted the attention of researchers. In the present research program, the morphology of Iron nanoparticles was confirmed by Scanning Electron microscopy (SEM). We are reporting a novel biological approach for the formation of Iron nanoparticles using solanum torvum flower extract. Copper sulphate was made to reduce with aqueous solution of solanum torvum flower extract. Scanning electron microscopy (SEM) suggested shape of the nanoparticle. Particle size analyzer confirms the particle size of the formed iron nanoparticles. UV-Visible absorption shows characteristic absorption peak of iron nanoparticles. Antibacterial studies confirm its potentiality against both Pseudomonas and Proteus bacteria.
