CHARACTERIZATION AND ANTIBACTERIAL ACTIVITY OF GREEN SYNTHESIZED IRON NANOPARTICLES FROM PTEROCARPUS MARSUPIUM BARK

Abstract

Nanotechnology has emerged as a state-of-the-art and cutting-edge technology with multifarious applications in a wide array of fields. Physical and synthetic processes are traditionally utilized for nanoparticles formation, anyway because of constraints of these techniques; nowadays, the main focus of research has been moved towards the improvement of safer and pure green synthesis methods. In recent years, the development of efficient green chemistry methods for synthesis of metal nanoparticles has become a major theme of researchers. One of the most considered methods is production of metal nanoparticles using cost efficient and environment favoring techniques like green synthesis. In this study, a very cheap and simple method was used to obtain the iron nanoparticles (FeNPs) using Pterocarpus marsupium bark. The iron nanoparticles were characterized by UV-Vis spectrophotometer, Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). The antibacterial activity was studied against Staphylococcus aureus and Shigella dysenteriae by using well-diffusion method. The UV-VIS spectrum of iron nanoparticles revealed a characteristic peak at 435nm. SEM study has showed a spherical shaped FeNPs and size of FeNPs were in the range of 180nm-233nm. XRD photograph indicated FeNPs were in crystalline face-centered cubic structure and the size of 16-17nm, further confirming the result of SEM. The FeNPs nanoparticles have shown a potential antibacterial activity when compared with their standards. Therefore, this simple, low cost and greener method for development of nanoparticles may be valuable in environmental, biotechnological and biomedical applications.
