Аннотация: The mechanism of N-phosphonomethyl iminodiacetic acid (PMIDA) binding with the Fe3O4 magnetic nanoparticle (MNPs) surface by Fourier transformed infrared spectroscopy, X-ray photoelectron spectroscopy and thermogravimetry was comprehensive studied. To study of microstructure, size and core structure of synthesized nanoparticles the scanning electron microscopy, X-ray diffraction analysis and Raman spectroscopy were carried out. A new scheme for the tridentate bonding of the phosphonomethyl derivative with surface Fe atoms involving unequal P–O–Fe bonds was proposed. The mechanism of thermal decomposition of PMIDA molecules on the MNP surface was studied using a thermogravimetric analyzer combined with infrared spectrometer. It was shown for the first time that during the thermal treatment of phosphonomethyl-modified MNPs, PMIDA molecules are not desorbed from the surface of MNPs but gradually decompose. We believe that obtained in this work data will be useful for a deeper understanding of the mechanisms of phosphonic acid derivatives interaction with MNPs, as well as in the design of new biomedical materials, in which the conjugation of biomolecules with carboxyl groups of PMIDA-modified MNPs is assumed.

MAGNETIC NANOPARTICLES -- RGD PEPTIDES -- PEPTIDE SYNTHESIS
Аннотация: Derivatives of RGD peptides are promising vector molecules for targeting biomolecules and nanoparticles into tumor tissues and are used for the design of diagnostic agents. The immobilization of the glutaryl-containing derivative of Gly-L-Arg(Pbf)-Gly-L-Asp(OMe)2 (GRGD) tetrapeptide on Fe3O4 magnetic nanoparticles (MNPs) was studied. The results of thermogravimetric and elemental analysis, as well as IR spectroscopy, were used to estimate the amount of organic components at each stage of modification of MNPs.

    Modification of chemically and physically obtained Fe3O4 magnetic nanoparticles with L-Lys for cell labeling / A. M. Demin, O. F. Kandarakov, A. S. Minin [et al.] // Russian chemical bulletin. - 2021. - Vol. 70, № 6. - P1199-1208
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Peculiar features of the modification of Fe3O4 magnetic nanoparticles (MNPs) obtained by co-precipitation from solutions of FeII and FeIII salts (10-nm MNPs) and by the gas-condensation method (30-nm MNPs) with 3-aminopropylsilane and then with L-lysine were studied. The chemically obtained MNPs possess more pronounced hydrophilic properties and therefore readily form stable aqueous colloidal solutions and can be loaded with a larger amount of L-Lys. However, samples based on the physically obtained MNPs were characterized by more efficient internalization and longer retention times by the NIH 3T3 cells. The results obtained can be used in the design of novel nanomaterials for magnetic cell labeling.

    Individual iron(III) glycerolate: synthesis and characterisation / T. G. Khonina, E. Y. Nikitina, D. S. Tishin [et al.] // RSC Advances. - 2022. - Vol. 12, № 7. - P4042-4046
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Iron(II) and iron(III) salts of strong acids form iron glycerolates on heating at 180 °C with glycerol in the presence of an equivalent amount of alkali. Individual iron(III) glycerolate was obtained for the first time. When Fe3O4 magnetic nanoparticles were heated with glycerol, an iron(III) glycerolate shell was formed on their surface.

    Peptide ligands on the PEGylated nanoparticle surface and human serum composition are key factors for the interaction between immune cells and nanoparticles / A. G. Pershina, A. M. Demin, N. A. Perekucha [et al.] // Colloids and Surfaces B: Biointerfaces. - 2023. - Vol. 221. - P112981
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The architecture of a nanoparticles' surface formed due to a modification with a ligand and protein corona formation in biofluids is critical for interactions with cells in vivo. Here we studied interactions of immune cells with magnetic nanoparticles (MNPs) covalently modified with polyethylene glycol (PEG) and their counterparts conjugated with peptides: a pH (low) insertion peptide (pHLIP) and cycloRGD as a targeting ligand in human serum. The conjugation of MNPs-PEG with pHLIP, but not with cycloRGD, enhanced the association of these particles with mononuclear phagocytic cells in vitro and in vivo. We did not find a clear difference in protein corona composition between the pHLIP-modified and parental PEGylated nanoparticles. Analysis of the effect of autologous human serum on MNP uptake by monocytes showed that the efficiency of endocytosis varies among healthy donors and depends on intrinsic properties of serum. Nevertheless, using classic blood, coagulation, biochemical tests, and anti-PEG IgG serum level, we failed to identify the cause of the observed interdonor variation. These individual differences should be taken into consideration during testing of nanotherapeutics.
