Аннотация: The surface properties of diamond nanoparticles (40-50 A in diameter) have been investigated by X-ray photoelectron spectroscopy (XPS), UV photoelectron spectroscopy (UPS) and Raman spectroscopy. The diamond nanoparticles have been deposited on flat Si(100) substrates by electrophoresis/dielectrophoresis. The as-deposited films are strongly oxidized and present a 1-2% nitrogen content. After treatment at 850 В°C in H2 plasma for 60 min, the oxygen is removed, and the position of the C 1s core-level peak indicates a n-type electronic comportment of the diamond nanoparticles. Raman spectroscopy of the as-deposited film shows a sp3 contribution at 1321 cm-1 and a sp2 contribution around 1620 cm-1. The 12 cm-1 shift of the sp3 contribution with respect to the bulk diamond peak at 1333 cm-1 is attributed to a phonon confinement effect due to the size of the diamond particles. The H2 plasma treatment induces a size decrease of the nanocrystallites confirmed by Raman and scanning electron microscopy (SEM) measurements. UPS spectroscopy shows a negative electron affinity of -0.2 eV of the hydrogenated nanodiamond film.

Аннотация: The physical properties of bulk composite materials consisting of nanodiamond, pyrolytic carbon, and nanopores were investigated. Samples were irradiated in a channel of the reactor by fast neutrons (E 0.5MeV) in ampoules with helium and in an aqueous medium. The dependences of the electrical transport properties of materials with different compositions on the dose of irradiation with fast neutrons were studied. A nonmonotonic change in the electrical resistivity with an increase in the neutron fluence was revealed. Possible explanations were offered for the observed dependence of the electrical resistivity on the neutron fluence, in particular, those related to the physical processes occurring in surface states of the three-phase system of the nanocomposite.

Аннотация: The nonlinear scattering of light under the conditions of optical limiting of nanosecond pulsed laser radiation at a wavelength of 1064 nm in a nanodiamond (ND) hydrosol has been experimentally studied. Superstable hydrosols were obtained from detonation NDs with a modified surface. Using an improved scheme of z scanning, it is shown that a decrease in the optical transmission coefficient of an ND hydrosol under optical limiting conditions is due to enhanced nonlinear scattering. It is established that the energy of pulsed radiation scattered at a right angle obeys a power law in dependence on the energy density of incident radiation pulses. Hydrosols of detonation NDs with the modified surface exhibit high stability with respect to the periodic laser action at high power density.

Аннотация: Hematological parameters and the state of liver cells of rats were examined in vivo after the animals received aflatoxin B(1) (AfB(1)) alone and together with modified nanodiamonds (MND) synthesized by detonation. The rats that had received the MND hydrosol had elevated leukocyte levels, mainly due to higher granulocyte counts and somewhat increased monocyte counts compared to control rats. Hematological parameters of the rats that had received AfB(1) alone differed from those of the control rats in another way: total white blood cell counts were significantly lower due to the decreased lymphocyte counts. In rats that had consumed AfB(1) with the MND hydrosol, changes in hematological parameters were less pronounced than in rats that had consumed either AfB(1) or MND. Electron microscopy showed that hepatocytes of the rats that had received the MND hydrosol or AfB(1) with the MND hydrosol contained elevated levels of lipid inclusions and lysosomes. Hyperplasia of the smooth endoplasmic reticulum (EPR) was revealed in liver specimens of the rats that had received AfB(1). Results of the study suggest the conclusion about mutual mitigation of the effects of nanoparticles and the mycotoxin on rats blood and liver cells after AfB(1) has adsorbed on MND.

Аннотация: Surface of detonation nanodiamonds was functionalized for the covalent attachment of immunoglobulin, and simultaneously bovine serum albumin and Rabbit Anti-Mouse Antibody. The nanodiamond-IgG(I125) and RAM-nanodiamond-BSA(I125) complexes are stable in blood serum and the immobilized proteins retain their biological activity. It was shown that the RAM-nanodiamond-BSA(I125) complex is able to bind to the target antigen immobilized on the Sepharose 6B matrix through antibody-antigen interaction. The idea can be extended to use nanodiamonds as carriers for delivery of bioactive substances (i.e., drugs) to various targets in vivo.

Linear pUC19 molecules with blunt ends, prepared by restriction of the initial ring form of pUC19 DNA, and linear 0.25-10 kb DNA fragments are adsorbed on nanodiamonds. The amount of adsorbed linear DNA molecules depends on the size of the molecules and the size of the nanodiamond clusters.

Аннотация: The purpose of this study was to develop micro and nano sized drug carriers from poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and study the cell and skin penetration of these particles. PHBV micro/nanospheres were prepared by o/w emulsion method and were stained with a fluorescent dye, Nile Red. The particles were fractionated by centrifugation to produce different sized populations. Topography was studied by SEM and average particle size and its distribution were determined with particle sizer. Cell viability assay (MTT) was carried out using L929 fibroblastic cell line, and particle penetration into the cells were studied. Transdermal permeation of PHBV micro/nanospheres and tissue reaction were studied using a BALB/c mouse model. Skin response was evaluated histologically and amount of PHBV in skin was determined by gas chromatography-mass spectrometry. The average diameters of the PHBV micro/nanosphere batches were found to be 1.9 mu m, 426 and 166 nm. Polydispersity indices showed that the size distribution of micro sized particles was broader than the smaller ones. In vitro studies showed that the cells had a normal growth trend. MTT showed no signs of particle toxicity. The 426 and 166 nm sized PHBV spheres were seen to penetrate the cell membrane. The histological sections revealed no adverse effects. In view of this data nano and micro sized PHBV particles appeared to have potential to serve as topical and transdermal drug delivery carriers for use on aged or damaged skin or in cases of skin diseases such as psoriasis, and may even be used in gene transfer to cells.

Аннотация: The optical limiting (OL) of detonation nanodiamond (DND) suspensions in engine oil was studied at a temperature range of 20°C to 100°C. Oil suspensions were prepared on the basis of the DNDs with an average nanoparticle cluster size in hydrosols (Daver) of 50 and 110 nm. Raman spectroscopy was used to characterize the samples. The OL investigation was carried out by the z-scan technique. The fundamental (1064 nm) and second (532 nm) harmonic radiations of YAG:Nd3 laser with passive Q-switching as an excitation source were used. The OL thresholds for both suspensions at 532 and 1064 nm were determined. It is shown that a decrease in the average nanoparticle cluster size as well as an increase of the wavelength of the incident radiation leads to the OL threshold increase. It is established that the OL performance is not influenced by increasing the temperature from 20°C to 100°C. The results obtained show the possibility of using the DNDs suspensions in engine oil as an optical limiter in a wide temperature range. © 2017 Society of Photo-Optical Instrumentation Engineers (SPIE).

Аннотация: Experimental data have been presented on the influence of silver on the viscosity and thermal conductivity of a dispersion of diamond nanoparticles. A stable dispersion (5 wt %) of detonation nanodiamond particles has been used in the experiments. Silver ions have been introduced electrolytically into the dispersion of diamond nanoparticles. Silver concentration was not higher than 0.05 wt %. It has been shown that the introduction of silver ions significantly affects the thermal conductivity and viscosity of the dispersion. © 2017, Pleiades Publishing, Ltd.

Аннотация: A new method for assessing biotoxicity of nanomaterials, based on the use of soluble bioluminescent coupled enzyme system NAD(P)ai...H:FMN oxidoreductase and luciferase, is proposed. The results of this study indicate a significant adverse biological effect exerted by nanoparticles at the molecular level. It was found that the most toxic nanoparticles the nanoparticles are based on copper and copper oxide, as well as single-walled carbon nanotubes and multi-walled carbon nanofibers, which are referred to hazard class II.

Bacterial magnetite -- Magnetic hysteresis -- Nanoparticles
Аннотация: The domain state of magnetite detected in sediments of Shira lake (Khakassia, Russia) was examined by means of magnetic hysteresis. Analysis of experimental data obtained on samples from different parts of bottom sediment cores in terms of Day plots allowed us to conclude that magnetite particles are in the pseudo-single-domain state. This indicates respectively small size of magnetite particles (< 100 nm) and reveals their bacterial origin. Biogenic magnetite buried in the bottom sediments can indicate the climatic changes in the Shira lake level in the Late Holocene. © Siberian Federal University. All rights reserved.

On the applicability of nanodiamonds produced by detonation synthesis for phenol testing in aqueous media / N. O. Ronzhin, A. P. Puzyr, V. S. Bondar // Dokl. Chem. - 2017. - Vol. 475, Is. 1. - P155-158, DOI 10.1134/S0012500817070011 . - ISSN 0012-5008
Аннотация: It was found that the catalytic effect of modified nanodiamonds (MND) in the H2O2–4-aminoantipyrine–phenol oxidative azo coupling reaction is due to microimpurities of iron and copper ions on the surface of nanoparticles. The efficiency of MND as a catalyst is determined by the amount of surface impurities of these ions and can be doubled by their additional adsorption on nanoparticles. Using MND for phenol indication ensures a linear yield of the colored product of the azo coupling reaction over an analyte concentration range of 0.05–10 ?g/mL. The possibility of reusing MND for phenol testing in aqueous samples was demonstrated. © 2017, Pleiades Publishing, Ltd.
