green synthesis of iron nanoparticles by aqueous extract of zingiber officinale: characterization and inhibitory effect on escherichia coli investigated

Purpose: the goal of biomedical researchers is to overcome harmful bacteria' resistance to antibiotics by developing new active chemicals quickly, cheaply, easily, and environmentally.materials and methods: in this instance, iron nanoparticles (fe-nps) were created using a green method by mixing an equal volume of zingiber officinale aqueous extract with a 100 ml solution of ferrous chloride tetrahydrate (fecl2.4h2o (0.4 m)). the distinctive dark brown color shift of the mixture indicated the production of fe-nps.results: this suggests that the nanocomposite was created and the reaction occurred. ft-ir, tem, and uv-vis spectroscopy were utilized to analyze phytosynthesized fe-nps. overall, the phytosynthesized fe-nps show activities that enable their use in various biomedical and biotechnological applications. additionally, the antimicrobial effect was investigated against gram-negative bacteria (escherichia coli).conclusion: the antibacterial activity of e. coli was determined, and the highest zone of inhibition was observed at the concentration of 100 μg/ml.
