We synthesized manganese ferrite (MnFe2O4) nanoparticles of different sizes by varying pH during chemical co-precipitation procedure and modified their surfaces with polysaccharide chitosan (CS) to investigate characteristics of hyperthermia and magnetic resonance imaging (MRI). Structural features ...

Biomedical applications of ZnFe2O4 nanoparticle are preferable among all kinds of ferrites due to the compatibility of Zn2+ ions for human bodies. We have followed the soft chemical route to synthesize chitosan and PEG coated ZnFe2O4 nanoparticles and also the chitosan-coated-nanoparticles encapsula...

The initiation of ferrite nanoparticles has changed the perception of nanotechnology in the biomedical field especially magnetic hyperthermia based application. Wet chemical co-precipitation method has been used to synthesize chitosan-coated Co1−xMnxFe2O4 (0.0 ≤ x ≤ 1.0, in the steps of 0.2) nano fe...

Cobalt ferrite nanoparticle (CFN) has received attention in magnetic resonance imaging (MRI) as a promising contrast agent due to its higher saturation magnetization and magneto-crystalline anisotropy. However, the in vitro cytotoxicity of CFN has raised concern for its biomedical application as a d...

In the current study, we explored the influence of structural, morphological, and magnetic properties of diamagnetic aluminum (Al3+) ions substituted nickel-zinc-cobalt (Ni-Zn-Co) spinel ferrites synthesized by the conventional ceramic technique. Single-phase cubic spinel structures with the Fd3m sp...

Optimum sintering temperature (Ts) plays an important role in controlling densification and growth of grains which greatly affect the magnetic and electrical properties of polycrystalline materials. Y-substituted Mg-Zn [Mg0.5Zn0.5YxFe2−xO4 (0 ≤ x ≤ 0.05)] ferrites have been prepared by using convent...

Zinc ferrite samples were prepared by two different routes which are chemical co-precipitation and standard solid state double sintering method. Structural properties of ZnFe2O4 were determined, and initial particle size was found as 5 nm in the samples prepared by chemical co-precipitation techniqu...
