Structural, stability, magnetic, and toxicity studies of nanocrystalline iron oxide and cobalt ferrites for biomedical applications
Source abstract
Abstract
Iron oxide and cobalt ferrite magnetic nanoparticles (MNPs) of 5–15 nm range have been synthesized by the co-precipitation method, and the magnetic MNPs are functionalized by 3-aminopropyl triethoxy silane and citric acid. The crystalline quality of the MNPs was confirmed using X-ray diffraction, verifying the spinel structure. Spectroscopy study confirmed the presence of the corresponding functional groups on MNP surfaces and thermogravimetric analysis further confirmed functionalization. Coercivity and saturation magnetization exhibited superior superparamagnetic properties. Toxicity studies compared the dose dependent toxicity of both pure iron oxide and cobalt ferrite samples. The toxicity of surface functionalized MNPs showed the potential for use in biomedicine.
