“…In a hydrothermal method, an aqueous mixture of the precursors containing the iron salts is tightly sealed in a Teflon-lined stainless steel autoclave chamber which is subjected to a temperature of up to 200 °C (mostly above the boiling point of water) for about few hours to a couple of days. [75,86,119] Consequently, high pressure is developed inside the autoclave chamber and a combination of high temperature-pressure results in the formation of Fe 3 O 4 nanoparticles. The percent yield recorded is relatively lower as compared to the coprecipitation technique.…”

“…When synthesizing iron oxide nanoparticles, a mixture of several phases (Fe 3 O 4 , γ-Fe 2 O 3 , α-Fe 2 O 3 ) is often obtained. In the case of γ-Fe 2 O 3 , impurity defects formation is an especially important process [ 45 ]. Since magnetite (Fe 3 O 4 ) and maghemite (γ-Fe 2 O 3 ) crystallize in lattices of similar types (reverse spinel), it is very difficult to distinguish these two oxides by X-ray diffraction [ 45 , 46 , 47 , 48 ].…”

The paper contains an overview of modern spectroscopic methods for studying the local atomic structure of superparamagnetic nanoparticles based on iron oxide (SPIONs), which are an important class of materials promising for theranostics in oncology. Practically important properties of small and ultra small nanoparticles are determined primarily by their shape, size, and features of the local atomic, electronic, and magnetic structures, for the study of which the standard characterization methods developed for macroscopic materials are not optimal. The paper analyzes results of the studies of SPIONs local atomic structure carried out by X-ray absorption spectroscopy at synchrotron radiation sources and Mössbauer spectroscopy during the last decade.

“…Auffan et al [5,7] We have recently reported on the preparation of MNPs doped with rare earth elements [23][24][25]. In particular, we obtained the Sm 3+ -doped (4-9 wt.%) Fe 3 O 4 MNPs with an average size falling in the 6-18 nm interval (depending on the EG/PEG ratio) by a polyol-mediated microwave-assisted (MW) synthesis [23] or those adjusted to 9 nm (when adding a capping agent) by a polyol-mediated solvothermal synthesis [24]. In another study, we obtained Gd 3+ -doped (4.2 wt.%) c-Fe 2 O 3 MNPs of 12 nm by a coprecipitation method [25].…”

Magnetic nanoparticles (MNPs) made of iron oxides with cubic symmetry (Fe 3 O 4 , c-Fe 2 O 3 ) are demanded objects for multipurpose in biomedical applications as contrast agents for magnetic resonance imaging, magnetically driven carriers for drug delivery, and heaters in hyperthermia cancer treatment. An optimum balance between the right particle size and good magnetic response can be reached by a selection of a synthesis method and by doping with rare earth elements. Here, we present a microwave-assisted polyol synthesis of iron oxide MNPs with actual gadolinium (III) doping from 0.5 to 5.1 mol.%. e resulting MNPs have an average size of 14 nm with narrow size distribution. eir surface was covered by a glycol layer, which prevents aggregation and improves biocompatibility. e magnetic hyperthermia test was performed on 1 and 2 mg/ml aqueous colloidal solutions of MNPs and demonstrated their ability to rise the temperature by 3°C during a 20-30 min run. erefore, the obtained Gd 3+ MNPs are the promising material for biomedicine.
