Abstract
This paper reports experimental details for preparation of poly-dispersed hematite (Fe2O3) nanoparticles using Nyctanthes arbor tristis flower extract at physiological pH and room temperature. The bio-inspired fabricated iron oxide nanomaterial is characterized by XRD patterns which reveal the formation of a high crystalline quality with rhombohedral structure having hematite phase. It is observed that XRD peak intensity is affected by the concentration of precursor. The FT-IR analysis reveals the existence of Fe-O bonding in the synthesized nanoparticles. The FE-SEM analysis reveals the nanostructure which is found to be poly-dispersed bead like agglomerates. The synthesized nanoparticles exhibit potential antimicrobial efficacies against Kleb. pneumoniae and Staph. aureus. Also the minimum inhibitory concentrations of the synthesized nanoparticles have been determined.
