Superparamagnetic Iron Oxide Nanoparticles Synthesis by Carrier Oils Stabilization

This work presents the synthesis, characterization, and implication of magnetic nanoparticles in identifying the antibiotic sensitivity on gram positive bacteria with different fatty acids stabilized nanoparticles. The iron oxide nanoparticles were combined utilizing co-precipitation technique and balanced out in different bio-surfactants, for example, flaxseed oil, almond oil and olive oil. These nanoparticles were characterized by X-ray diffraction method, FTIR analysis, particle size analyzer and Transmission Electron Microscopy. Structure of initial magnetite nanoparticles synthesized was confirmed by XRD analysis and the estimation of nanoparticles size with the value of 50 -100 nm and it was confirmed with TEM. The attachment of functional groups of oils was predicted using FTIR spectroscopy. Studies indicate that olive oil and almond oil stabilized iron oxide nanoparticles show effective antibacterial activity toward the gram- positive bacterium bacillus cereus compared to flaxseed oil. The results suggest that iron oxide NPs with surface coatings could potentially be used as an effective antibacterial agent
