Abstract

Syed Md Humayun Akhter, Faiz Mohammad and Shamim Ahmad

Green synthesis of metal oxide nanoparticles has been emerging highlight of the research owing to its unique properties that make them applicable in various fields of science and technology. The method of synthesis is simple, cost effective and environmental friendly. After review, we reported the phyto-synthesis of metal oxide nanoparticles using plant extract with an emphasis on recent developments. Biomolecules such as alkaloids, flavonoids, polyphenols etc. present in the plant extract can be used for the reduction of metal ions to nanoparticles in a single step process. These extract also act as a stabilizing agent. Although, a good number of work has been reported for the synthesis of gold and silver nanoparticles. However, limited no of work has been reported for the synthesis of copper, zinc and iron oxide nanoparticles. We have discussed the green synthesis of copper, zinc and iron oxide nanoparticles and potential of their antibacterial efficacy.
