The present study emphasizes on eco-friendly production of iron oxide nanoparticles utilizing Leucas aspera (La-IO NPs) extract. This method utilizes a sustainable approach, leveraging the bio-reducing and stabilizing properties of the plant. Phyto-chemical screening of Leucas aspera uncovered the existence of numerous secondary metabolites, indicating their potential role in the reduction and stabilization of iron salts and a noticeable alteration in colour was recorded during synthesis the FeCl3 solution turned from yellow to brownish black signifying La-IO NPs synthesis. Characterization of nanoparticles such as UV-Visible spectroscopy, FTIR, XRD was done for understanding their properties and SEM analysis revealed the morphology of irregular rhombic shapes with panoramic view and size range from 105 to 145 nm.

This method utilizes a sustainable approach, leveraging the bio-reducing and stabilizing properties of the plant. Phyto-chemical screening of Leucas aspera uncovered the existence of numerous secondary metabolites, indicating their potential role in the reduction and stabilization of iron salts and a noticeable alteration in colour was recorded during synthesis the FeCl3 solution turned from yellow to brownish black signifying La-IO NPs synthesis. Characterization of nanoparticles such as UV-Visible spectroscopy, FTIR, XRD was done for understanding their properties and SEM analysis revealed the morphology of irregular rhombic shapes with panoramic view and size range from 105 to 145 nm.
