Chemical Preparation of Iron Oxide Nanoparticles Using Plants Extracts in Antibacterial Application

In of this studying the green synthesis of Iron Oxide nanoparticles (Fe2O3 NPs) with Celery stalks and green tea leaves extract were used. The fresh suspension of plant extracts ware green- brown in color. However, after acting of FeNO3 within 20min, the suspension showed the change in color and turned dark brown after 4 hours of incubation at room temperature. Formation of Iron oxide nanoparticles was confirmed using X-ray is spectral analysis and showed the characteristic Bragg peaks of (111) to green tea extract and (111) to celery extract, plant of the face center cubic (FCC) Iron Oxide nanoparticles. The scanning electron microscope (SEM) Iron oxide nanoparticles see small particles and rode. The synthesized Fe2O3 NPs colloidal solution has shown better antibacterial activity against both Gram-positive and Gram-negative bacterial strains. The diameters of the inhibition zones of Fe2O3 NPs against the bacterial strains were, S. aureus (27 mm) p. aerugino (29mm) with camellia sinensis extract and S. aureus (22 mm) p. aerugino (25mm) with Apium graveolens exiract at 50 μg/ml concentration
