Заглавие : Detection of nanodiamonds in biological samples by EPR spectrometry
Место публикации : Doklad. Biochem. Biophys.: Maik Nauka Publishing / Springer SBM, 2017. - Vol. 477, Is. 1. - С. 394-397. - ISSN 16076729 (ISSN) , DOI 10.1134/S1607672917060138
Аннотация: In model experiments in vitro, the applicability of the EPR spectrometry method for the detection of modified nanodiamonds (MNDs) in blood and homogenates of mouse organs has been established. A characteristic signal (g = 2.003, ?H ? 10 G) is observed in the samples of biomaterials containing MNDs, the intensity of which increases linearly with the concentration of nanoparticles in the range of 1.6–200 ?g MNDs per 1 mL of the sample. The EPR method in biomaterials reveals the presence of intrinsic paramagnetic centers, signals from which are superimposed on the signal from the MNDs. However, the intensity of these signals is small, which makes it possible to register the MNDs using EPR spectrometry with the necessary accuracy. The data obtained open up the prospects of using the EPR method for studies of the interorgan distribution, accumulation, and elimination of MNDs during their intravenous injection into experimental animals. © 2017, Pleiades Publishing, Ltd.

Заглавие : On the applicability of nanodiamonds produced by detonation synthesis for phenol testing in aqueous media
Место публикации : Dokl. Chem.: Maik Nauka Publishing / Springer SBM, 2017. - Vol. 475, Is. 1. - С. 155-158. - ISSN 00125008 (ISSN) , DOI 10.1134/S0012500817070011
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.

Аннотация: Modified nanodiamonds (MNDs) produced by detonation synthesis can be used as an effective adsorbent to immobilize extracellular peroxidases of the luminous basidiomycete Neonothopanus nambi. The enzymes are firmly immobilized on MND particles and exhibit catalytic activity. The indicator system (the MND-enzyme complex) reused many times retains its ability to catalyze reaction of co-oxidation of phenol and 4-aminoantipirine in the presence of hydrogen peroxide and remains functionally active during long-term storage (for 1 month or longer) in aqueous suspensions at 4 degrees C. MNDs and enzymes of higher fungi can be effectively used to construct new reusable indicator systems for analytical applications such as monitoring contamination of aquatic environments by phenolic compounds.

Аннотация: A bifunctional indicating complex was created by immobilization of extracellular oxidases (glucose oxidase and peroxidases) of luminous fungus Neonothopanus nambi onto modified nanodiamonds (MNDs) synthesized by detonation. It was found that the enzymes firmly adsorb onto MND particles and exhibit their catalytic activity. Model in vitro experiments showed that the created MND-enzymes complex is suitable for repeated use for analyte (glucose and phenol) testing and retains its activity after storage at 4 degrees C in deionized water for 1 month. The data obtained offer the prospects for developing a new class of reusable multifunctional indicating and diagnostic test systems on the basis of MNDs and higher fungal enzymes for medical and ecological analytics.

Ключевые слова (''Своб.индексиров.''): detonation nanodiamonds--catalytic activity--metal ions--azo coupling--reaction--phenol detection
Аннотация: This paper demonstrates the effectiveness of using detonation nanodiamonds (DNDs) for detecting phenol in aqueous medium. The study has shown that the catalytic effect of DNDs in the oxidative azo coupling reaction (phenol-4-aminoantipyrine-hydrogen peroxide) is produced by trace amounts of iron and copper ions adsorbed on the surface of nanoparticles. The effectiveness of DNDs as a catalyst is determined by the amounts of these adsorbates and can be enhanced by a factor of two by additional adsorption of these ions onto the nanoparticles. A rise in the temperature of the ONO-catalyzed azo coupling reaction leads to a considerable (4.5-fold) increase in the reaction product yield. DNDs used to detect phenol in aqueous medium enable a linear increase in the yield of the product of the azo coupling reaction at concentrations of the analyte of between 0.05 and 10 mu g/mlThe study demonstrates that DNDs can be reused to detect phenol in water samples.

Аннотация: Adsorption of viral particles from the blood plasma of patients with viral hepatitis B and C on modified nanodiamonds (MNDs) was shown in the in vitro experiments. PCR method showed the treatment of plasma with MNDs leads to a decrease in the viral load by 2–3 orders of magnitude or more in both cases studied. These results make it possible to predict the applicability of MNDs for the development of new technologies of hemodialysis and plasmapheresis for binding and removal of viral particles from the blood of infected patients. © 2016, Pleiades Publishing, Ltd.

Аннотация: A reusable system including urease covalently bound to the surface of modified nanodiamonds (MNDs) has been developed for the multiple determination of urea. The immobilized enzyme exhibits functional activity and catalyzes the hydrolysis of urea to yield ammonia. The presence of ammonia is confirmed by the formation of a colored product after the addition of chemical reagents. It was shown that the MNDs-urease complex can function in a wide range of temperatures and pH as well as in deionized water. The complex provides a linear yield of the product at low analyte concentrations and allows the multiple determination of urea in vitro. © 2015, Pleiades Publishing, Ltd.

Аннотация: We report on a saturable absorption in aqueous dispersions of nanodiamonds with femtosecond laser pulse excitation at a wavelength of 795 nm. The open aperture Z-scan experiments reveal that in a wide range of nanodiamond particle sizes and concentrations, a lightinduced increase of transmittance occurs. The transmittance increase originates from the saturation of light absorption and is associated with a light absorption at 1.5 eV by graphite and dimer chains (Pandey dimer chains). The obtained key nonlinear parameters of nanodiamond dispersions are compared with those of graphene and carbon nanotubes, which are widely used for the mode-locking. © 2017 Society of Photo-Optical Instrumentation Engineers (SPIE).

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: The distribution in mice of intravenously injected modified nanodiamonds (MNDs) obtained by detonation synthesis was studied using electron paramagnetic resonance (EPR) spectrometry. It has been shown that 2.5 h after MND injection into the tail vein of mice, the nanoparticles accumulate mainly in the lungs and liver of animals; much smaller amounts of nanoparticles were found in the kidneys and heart. The presence of MNDs in the samples of blood, spleen, brain, and thigh muscles of mice was not detected within the sensitivity of the method used.

Аннотация: The development of inexpensive, easy-to-produce, and easy-to-use analytical tools for detection of harmful and toxic substances is a relevant research problem with direct applications in environmental monitoring and protection. In this work, we propose a novel composite material based on alumina nanofibers and detonation nanodiamonds for detection of phenol in aqueous medium. The composite material was obtained by mixing an aqueous suspension of alumina nanofibers with a diameter of 10-15 nm and a length of several microns and a hydrosol of nanodiamonds with an average cluster size of 70 nm. The mechanisms underlying the interaction of these nanomaterials are clarified and the physicochemical properties of the composite are investigated. The SEM and TEM studies show that the obtained composite has a network structure, in which clusters of nanodiamonds (10-20 nm in diameter) are distributed over the surface of nanofibers. Coupling of nanomaterials occurs due to opposite signs of their zeta potentials, which results in electrostatic attraction and subsequent chemical bonding as indicated by the X-ray photoelectron spectroscopy and simultaneous thermal analysis. The bonding apparently occurs between functional groups (mainly carboxyl) on the surface of nanodiamonds and amphoteric hydroxyl groups on the surface of alumina nanofibers. The proposed composite allows an easy-to-perform colorimetric analysis for qualitative and quantitative determination of phenol in aqueous samples with linear response over a wide range of concentrations (0.5-106 mu M). Multiple tests have shown that the composite is reusable and retains its catalytic function for at least 1 year during storage at room temperature.

EXPRESSION
Аннотация: A reusable system for phenol determination in an aqueous medium was obtained by adsorption of extracellular oxidase from fungus Neonothopanus nambi onto modified nanodiamonds (MND) synthesized by detonation. It was found that the enzyme strongly binds to MND and exhibits catalytic activity in the reaction of co-oxidation of phenol with 4-aminoantipyrine without the addition of hydrogen peroxide. In the presence of the MND-oxidase complex, a significantly (by an order of magnitude) higher yield of the reaction product is recorded as compared to the yield in the presence of a free enzyme; the mechanism of the revealed effect is discussed. Model experiments have demonstrated the multiple use of the MND-oxidase complex for testing phenol in aqueous samples. The immobilized enzyme exhibits functional activity during long-term (2 months) storage of the MND-oxidase complex at 4 degrees C. The data obtained create the prerequisites for using the created system in environmental monitoring of water pollution with phenol.

Аннотация: The application of detonation nanodiamonds (DNDs) in delivery systems has been demonstrated many times for a variety of substances, including anti-inflammatory drugs, antibiotics, antineoplastic agents, vitamins etc. The applicability of detonation nanodiamonds as a carrier for delivery of corticosteroids is investigated in this study. Commercial DNDs were modified to obtain particles with high colloidal stability in aqueous suspensions. Physical adsorption was then used to conjugate the DNDs with methylprednisolone sodium succinate and dexamethasone sodium phosphate. The experimental adsorption isotherms were fit with Langmuir and Freundlich adsorption models. The results of in vitro release study demonstrated an explicit prolonged effect of DNDs, due to which a sustained release of the adsorbed drugs was provided.

Аннотация: Biodistribution of nanodiamonds in mice after intravenous administration, activities of AST and ALT, and the level of bilirubin in the blood plasma were studied in 2.5 h and 10, 35, and 97 days after injection of nanodiamonds. In 2.5 h after intravenous injection, nanodiamonds mainly accumulate in the lungs and liver. Then, redistribution of nanodiamonds from all organs to the liver was observed. Activities of AST and ALT and the level of bilirubin in the blood increased after 2.5 h and then decreased to the initial values.
