Заглавие : A gold nanoparticle-based molecular self-assembled colorimetric chemosensor array for monitoring multiple organic oxyanions
Место публикации : Processes. - 2022. - Vol. 10, № 7. - Ст.1251

Ключевые слова (''Своб.индексиров.''): chemosensor array--gold nanoparticles--organic oxyanions
Аннотация: Determination of oxyanions is of paramount importance because of the essential role they play in metabolic processes involved in various aquatic environmental problems. In this investigation, a novel chemical sensor array has been developed by using gold nanoparticles modified with different chain lengths of aminothiols (AET-AuNPs) as sensing elements. The proposed sensor array provides a fingerprint-like response pattern originating from cross-reactive binding events and capable of targeting various anions, including the herbicide glyphosate. In addition, chemometric techniques, linear discrimination analysis (LDA) and the support vector machine (SVM) algorithm were employed for analyte classification and regression/prediction. The obtained sensor array demonstrates a remarkable ability to determine multiple oxyanions in both qualitative and quantitative analysis. The described methodology could be used as a simple, sensitive and fast routine analysis for oxyanions in both laboratory and field settings.

Аннотация: Surface modifi cation of magnetic nanoparticles (MNPs) with tetramethylorthosilicate and 3-aminopropyltrimethoxysilane was studied. The use of N-phosphonomethyliminodiacetic acid for the stabilization of the initial MNPs can signifi cantly increase the coating thickness and specifi c surface area of SiO2/APS-modifi ed (APS is 3-aminopropylsilane) MNPs. The possibility of sorption of antitumor drug doxorubicin (DOX) on the synthesized nanoparticles was studied. The degree of sorption of DOX increases with an increase in the specifi c surface area of the particles.

Аннотация: Methods for synthesis of nanosized precursors for the preparation of yttrium-aluminum garnet from organic-inorganic derivatives of yttrium and aluminum have been developed. It has been shown that most of the methods for carrying out the process result in the formation of precursors with high specific surface area. The precursor obtained using nanosized powder of aluminum oxide and yttrium acetylacetonate is the least agglomerated. The data obtained can be used when preparing optical ceramic from yttrium-aluminum garnet

Ключевые слова (''Своб.индексиров.''): ftir--magnetic nanoparticles--mechanism of immobilization--pmida--tga--xps
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.

Заглавие : Modification of chemically and physically obtained Fe3O4 magnetic nanoparticles with L-Lys for cell labeling
Место публикации : Russian chemical bulletin. - 2021. - Vol. 70, № 6. - С. 1199-1208
Предметные 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.

Заглавие : Peptide ligands on the PEGylated nanoparticle surface and human serum composition are key factors for the interaction between immune cells and nanoparticles
Место публикации : Colloids and Surfaces B: Biointerfaces. - 2023. - Vol. 221. - С. 112981
Предметные 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.

Ключевые слова (''Своб.индексиров.''): supported iridium nanoparticles--n-arylhydroxylamine--semi-hydrogenation
Аннотация: Polystyrene stabilized Iridium (Ir@PS) nanoparticles (NPs) as a heterogeneous catalyst have been developed and characterized by IR, UV–Vis, SEM, TEM, EDX and XRD studies. The prepared Ir@PS catalyst showed excellent reactivity for chemo- and regio-selective controlled-hydrogenation of functionalized nitroarenes to corresponding N-arylhydroxylamine using hydrazine hydrate as reducing source and environmentally benign polyethylene glycol (PEG-400) as green solvent. The present methodology was applied for vast substrate scope and found to be compatible with wide range of reducible functional groups. The reaction performed at 85 °C or ambient temperature and completed within 5–80 minutes. The catalyst can easily be filtered out from reaction mixture and reusable.

Аннотация: The influence of magnetic field on the rate of oxidative dehydrogenation of 2,3,5-trimetyl-1,4-hydroquinone (TMHQ) to 2,3,5-trimetyl-1,4-benzoquinone (TMBQ) with catalysts based on copper oxide nanopowders has been investigated. The initial transformation rate of TMHQ and the final product yield greatly increase after a preliminary magnetization of nanopowders. The adsorption ability of Cu-oxide-based nanopowders with respect to ammonia enhances by 1.5 after their magnetization. Physical mechanism of reactivity variation of CuO nanopowders under the influence of weak stationary external magnetic field (H?3 kOe) has been proposed. As a result of magnetic field influence, the ferromagnetic regions with modified spin and charge state have appeared in an antiferromagnetic CuO of nonstoichiometric composition. These regions can be new catalytic or adsorption centers

Заглавие : Synthesis and antimicrobial activity of silicon-titanium-zinc- and silicon-titanium-boron-containing glycerohydrogels
Место публикации : Russian chemical bulletin. - 2021. - Vol. 70, № 5. - С. 967-974
ББК : Г
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Novel pharmacologically active silicon—titanium—zinc- and silicon—titanium—boron-containing glycerohydrogels were synthesized by the sol—gel method using silicon, titanium, zinc, and boron glycerolates as biocompatible precursors. The compositions and structural features of the hydrogels were studied by transmission electron microscopy, scanning electron microscopy, IR spectroscopy, atomic emission spectrometry, and elemental analysis methods. The disperse phase and liquid water—glycerol medium of the hydrogels were isolated by cold exhaustive extraction with ethanol and characterized. The 3D polymeric network of the gels is formed by the products of hydrolysis and subsequent (co)condensation of silicon-/silicon—boron-containing precursors. Titanium and zinc glycerolates undergo no hydrolytic transformations under gelation conditions and exist in the cells of the 3D polymeric network in the form of amorphous nanoparticles that are not linked to the network by covalent bonds. Models of the structures were proposed. The gels are characterized by antimicrobial activity, which is more pronounced for the silicon—titanium—boron-containing gel, and they can be considered as promising drugs for topical treatment prepared by the simple, environmentally friendly, and cost-effective method.

Аннотация: Magnetic iron nanoparticles (MNPs) encapsulated in a carbon shells and containing sulfo groups on the surface (Fe@C-SO3H) were synthesized. The aggregative stability of aqueous suspensions of the Fe@C-SO3H nanoparticles was studied in solutions of bovine serum albumin and calcium chloride and in phosphate-buffered saline, which simulate blood plasma. It is shown that the Fe@C-SO3H particles practically do not aggregate in the phosphate buffer saline for a long time (several days). On the contrary, MNPs encapsulated in a protein shells using ultrasonic treatment form aggregates up to 110–120 nm in size under these conditions. Suspensions of the Fe@C-SO3H particles are stable in aqueous solutions of calcium chloride in the range of the solid phase concentration between 0.05 and 0.10 g L−1. The results obtained indicate the possibility of using the functionalized Fe@C-SO3H nanoparticles in vitro experiments in biological media.
