Synthesis and characterization of iron oxide nanoparticles capped with Moringa Oleifera: The mechanisms of formation effects on the optical, structural, magnetic and morphological properties

Abstract

We successfully studied the synthesis of biocompatible and eco-friendly single route method for the subjugation of ferric chloride solution using a natural extract from Moringa Oleifera (MO) as an implied capping agent. We compared the significant effect of the sundry (SD) and room temperature (RT) on the biochemical properties of the MO as a capping agent. The physicochemical properties of the effects in the mechanism of preparation of FeO-NPs were studied using XRD, FTIR, SEM and VSM. The characterization results showed that the mechanism of formation has momentous influences on the formation of the phase spinel as well as on its physical properties for biomedical applications. The SEM gave an average particle diameter of 16–18 nm for the RT sample while the SD sample gave a size of 18–20 nm. The XRD showed a crystallinity with BCC lattice shape for the RT sample while the SD exhibit quasi-crystalline. The magnetic properties investigated by VSM gave no hysteresis loop indicating the superparamagnetic behaviors with 72.07 emu/g values of saturation magnetization with negligible remanence and coercivity values for the RT sample. The structural and superparamagnetic properties of synthesized MO-FeO-NPs coupled with their favorable particle size obtained in the investigation of the particles from RT-MO induced gave it a good method compared to SD-MO for discrete biomedical applications such as drug delivery.
