“…As a result, the core size decreases. A similar process was demonstrated by us in [52]. In the second case, this process is less pronounced, since, in addition to the Fe(III)Glyc shell, a SiGlyc-based shell is formed to a large extent.…”

Novel magnetic nanocomposite materials based on Fe3O4 nanoparticles coated with iron and silica glycerolates (MNP@Fe(III)Glyc and MNP@Fe(III)/SiGlyc) were obtained. The synthesized nanocomposites were characterized using TEM, XRD, TGA, VMS, Mössbauer and IR spectroscopy. The amount of iron and silica glycerolates in the nanocomposites was calculated from the Mössbauer spectroscopy, ICP AES and C,H-elemental analysis. Thus, it has been shown that the distribution of Fe in the shell and core for MNP@Fe(III)Glyc and MNP@Fe(III)/SiGlyc is 27:73 and 32:68, respectively. The synthesized nanocomposites had high specific magnetization values and a high magnetic response to the alternating magnetic field. The hydrolysis of shells based on Fe(III)Glyc and Fe(III)/SiGlyc in aqueous media has been studied. It has been demonstrated that, while the iron glycerolates shell of MNP@Fe(III)Glyc is resistant to hydrolysis, the silica glycerolates shell of MNP@Fe(III)/SiGlyc is rather labile and hydrolyzed by 76.4% in 24 h at 25 °C. The synthesized materials did not show cytotoxicity in in vitro experiments (MTT-assay). The data obtained can be used in the design of materials for controlled-release drug delivery.

“…A promising trend in biomedicine is the core–shell modification of Fe 3 O 4 MNPs for MRI diagnostics or magnetic hyperthermia of tumors. 12–14 So, the development of an iron glycerolate shell on the surface of Fe 3 O 4 MNPs 15 and studying an opportunity of using modified nanoparticles in magnetic hyperthermia is of particular interest. In addition, the antibacterial activity of Fe 3 O 4 MNPs with glycerol adsorbed on the surface was also demonstrated.…”

“…The available literature data concern only mixed iron( ii , iii ) glycerolate that is usually formed as a result of the interaction of di- or trivalent iron oxides, hydroxides or salts (mainly oxalates) with glycerol at elevated temperatures (up to 245 °C). 15,18–20 It is worth noting that all attempts to synthesize iron glycerolates from chlorides and sulfates of ferrous or ferric irons proved to be unsuccessful. 20 At the same time, iron glycerolate was obtained from iron( iii ) nitrate in boiling glycerol under reflux (280 °C); 3 however, contents of iron( iii ) and iron( ii ) were not determined in that product.…”

“…Magnetic materials based on Fe 3 O 4 nanoparticles with a biologically compatible coating are of great interest for biology and medicine. 12–14 Previously, we were the first to demonstrate the possibility of forming a shell of iron glycerolate on the surface of Fe 3 O 4 MNPs by a simple and reproducible method, namely, by interacting Fe 3 O 4 MNPs with glycerol at 220 °C for 40 h. 15 In this work, we optimized the synthetic procedure and chose the optimum conditions (180 °C, 18 h) (see ESI†). The composition of the resulting shell was found to correspond to iron glycerolate 1 .…”
