Green synthesis of nanoparticles utilizing plant extract has shown enormous advantages over the methods of synthesis. Green nanoparticles are generally synthesized using metal atoms like silver, iron, copper, zinc, and plant extract containing reducible phytoconstituents like alkaloids, flavonoids, tannins, etc. Several Iron nanoparticles are reported using plant extracts. Iron nanoparticles have a greater advantage of small size, affordable cost stability, or having some biomedical application. Such as tissue repair, hypothermia, cell separation, and most important is the integral component of our body system. In the present review, the account of methodologies for the synthesis of iron nanoparticles and the various plant extract having antimicrobial activity has been discussed.
