Biosynthesis and characterization of iron oxide nanoparticles using Eichhornia crassipes leaf extract and assessing their antibacterial activity

The study elaborated the processes of biogenic iron oxide nanoparticle (FeNPs) formation via green chemistry approach and analyzed their antibacterial activity. The biosynthesized iron oxide nanoparticles (FeNPs) were characterized by UV-visible spectroscopy, FT-IR (Fourier transform infrared spectroscopy), X-ray Diffractometer (XRD), EDX (Energy dispersive X-ray spectroscopy) and SEM (Scanning electron microscopy). The synthesized nanoparticles were rod shaped. The antibacterial activity was determined for Eichhornia mediated iron oxide nanoparticles (FeNPs). The highest zone of inhibition was observed at 100 µg/ml concentration of Eichhornia mediated iron oxide nanoparticles against Staphylococcus aureus and Pseudomonas fluorescens. The iron oxide nanoparticles (FeNPs) showed good antibacterial activity and may be used in medicinal fields.
