“…After investigated in vivo tumor the ranostics studies, the researchers have confirmed the potential in vivo use of the prepared samples for MRI studies. L. Ansari et al [106] has prepared a hybrid of Zinc-Cobalt ferrite functionalized with DMSA for in vivo MRI studies. The prepared samples have size between 5 -10 nm and MR imaging study was done on rats.…”

This chapter aims at the latest amelioration in the biomedical application of spinel ferrites. Magnetic hyperthermia treatment of tumour cells and contrast resonance imaging of human body parts, are a few applications of spinel ferrites that have gained substantial interest nowadays. The thermo-therapeutic and radiology based diagnosis treatment has many benefits over traditional methods used for disease diagnosis and imaging treatment of chronic carcinogenic origin diseases. The various types of doped and undoped spinel ferrite nanoparticles are investigated and optimised for different biomedical applications. Through this chapter, an attempt is made to provide readers the knowledge about various required characteristics and latest used strategies for the successful implementations of spinel ferrite in biomedical applications at commercial levels.

“…Reddy et al[54] and Monisha et al[50] both noted a comparable lattice constant value. For CoFe 2 O 4 , whereas Manouchehri et al[55] reported the average crystallite size of CoFe 2 O 4 nanoparticles coated with dimercaptosuccinic acid to be 13 nm, Monisha et al[50] found a crystallite size of 16.7 nm. According to Naseri et al[56], the crystallite size of MnFe 2 O 4 nanoparticles is 20 nm.…”

Hydrotalcite-like materials such as layered double oxides (LDOs) are promising materials for many technological applications. Linking the multilayer structure of LDOs with the exceptional optical, magnetic, and dielectric properties of spinel ferrites could result in advanced nanocomposites for photovoltaic, magneto-recording, and high-frequency applications. For that purpose, nanocomposites of type manganese chromium-layered double oxide/cobalt spinel ferrite, (MnCr)-LDOx/CoFe2O4 (x = 1, 3, and 5 wt%), were produced by the co-precipitation route. X-ray diffraction (XRD) analysis showed the successful incorporation of MnCr-LDO in CoFe2O4 lattice. After a 5 wt% addition of MnCr-LDO, the lattice parameter of pure CoFe2O4 increased from 8.3832 Å to 8.4136 Å, the crystallite size increased from 18.7 nm to 21.7 nm, and the strain dropped from 2.15 to 2.04. Transmission electron microscopy (TEM) revealed cubic morphologies for (MnCr)-LDOx/CoFe2O4 nanocomposites. Two strong absorbance peaks appeared in the Ultraviolet- visible (UV-vis) spectra (at ∼270 and ∼370 cm−1). The energy band gap and Urbach energy were estimated for the prepared samples. The composite sample (MnCr)-LDO1 wt%/CoFe2O4 recorded the highest band gap values (Eg1 = 3.39 eV, Eg2 = 4.46 eV, and Eg3 = 5.89 eV), while the (MnCr)-LDO3 wt%/CoFe2O4 sample had a relatively high Urbach energy value (1.35 eV). Vibrating sample magnetometer (VSM) analysis showed room temperature ferromagnetic (RTFM) behavior for the prepared composites. The saturation magnetization (Ms) value declined as the MnCr-LDO addition to CoFe2O4 increased, and the (MnCr)-LDO3 wt%/CoFe2O4 sample acquired the highest Ms (64.428 emu g−1) among all the produced composites. Pure CoFe2O4 had a much higher coercivity (Hc = 1158.1 Oe) than (MnCr)-LDOx/CoFe2O4 (x = 1, 3, and 5 wt%) nanocomposites (Hc = 1119.8, 978.48, and 984.16 Oe). Moreover, complex impedance spectroscopy measurements were performed in frequency range of 50 Hz- 5 MHz using Nyquist plots and electric modulus analysis. Nyquist plots were fitted to an analogous electric circuit consisting of a resistor R1 connected in series to two parallel constant phase element- resistor circuits (CPE-R). On the other hand, a different circuit comprises of two CPE, capacitor (C1), and resistor all connected in parallel was used to model CoFe2O4.
