“…Calcium-substituted magnesium ferrite nanoparticles (Ca x Mg 1−x Fe 2 O 4 ) not only can promote an increase in ferrite biocompatibility, but also improve the magnetic properties [15,16]. It is reported that upon doping with nonmagnetic Zn 2+ ions, magnesium ferrite nanoparticles showed an enhanced magnetization as a result of changes in ion site distribution [17,18].…”

Despite the promising pharmacological properties of curcumin, the transport and effective release of curcumin is still a challenge. The advances in functionalized nanocarriers for curcumin have also been motivated by the anticancer activity of this natural compound, aiming at targeted therapies. Here, stealth (aqueous and solid) magnetoliposomes containing calcium-substituted magnesium ferrite nanoparticles, CaxMg1−xFe2O4 (with x = 0.25, 0.50, 0.75) were developed as nanocarriers for curcumin. The magnetic nanoparticles exhibit superparamagnetic properties and crystalline structure, with sizes below 10 nm. The magnetoliposomes based on these nanoparticles have hydrodynamic diameters around or below 150 nm and a low polydispersity. The influence of an alternating magnetic field (AMF) on drug release over time was evaluated and compared with curcumin release by diffusion. The results suggest the potential of drug-loaded magnetoliposomes as nanocarriers that can be magnetically guided to the tumor sites and act as agents for a synergistic effect combining magnetic hyperthermia and controlled drug release.

“…A series of Mg-ferrite substituted by Cr, MgFe 2−x Cr x O 4 (with x = 0, 0.2, 0.4, 0.6, 0.8, 1.0) were prepared using the conventional double sintering technique, as described in [5]. XRD data were recorded on a Philips diffractometer (model pw 1820), using Cu-Kα radiation.…”

The structural and magnetic behaviour of the MgFe2 − xCrxO4 spinel ferrite

The crystal structure and magnetic properties of the spinel system MgFe 2−x Cr x O 4 (with x = 0, 0.2, 0.4, 0.6, 0.8, 1.0) have been investigated by means of X-ray diffraction (XRD), and Mössbauer spectroscopy. The XRD patterns showed the samples were single-phase cubic spinels. The 295 K Mössbauer spectra of the studied samples showed a continuous collapse of the internal magnetic field for both tetrahedral (A) and octahedral [B] sites with increasing Cr contents. Their 78 K Mössbauer spectra showed an ordered magnetic structure for both sites with the internal magnetic fields decreasing with increasing Cr contents. The continuous decrease in the internal magnetic field is interpreted in terms of the weakening of A-B exchange interaction. The cation distribution at tetrahedral (A) and octahedral [B] sites and its effect on Mössbauer parameters is studied. Mg 2+ ions are found to occupy both sites A and B, while Cr 3+ ions occupy site B only.

“…Metal nitrates were used in a 1:1 mol ratio with citric acid. To keep the pH at 7, a solution of metal nitrates was added drop by drop to a solution of 1 M sodium hydroxide to produce nanoparticles that are chemically homogeneous and less scattered in size [ 27 ]. The dry (MZFO) powder was obtained from the previously described sol-gel technique maintain the temperature of heated hot plate at 90 °C.…”
