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.

Аннотация: The application of nanobiotechnology is an emerging area of nanoscience and nanotechnology. Nanodi-amond has been a potent antibacterial, antifungal, antioxidant, and antiplatelet agent. In the present study, nanodiamonds were reduced by green synthesis and characterization was done through SEM, TEM, FTIR, and XRD. Further they were tested for their biological applications. The antimicrobial activity was investigated/studied/examined? through well diffusion method. The best activity was observed against Trichoderma reesei (16 mm) at 140 ?g/ml. The antioxidant activity was investigated through DPPH and FRAPS method. It was observed that the biologically reduced nanodiamonds reduce the Fe3+ ions to Fe2+ ions at 600 mM/l/g concentration. In DPPH assay, inhibitory concentration was found to be 4.58 ?g/ml. Further the antiplatelet activity was investigated by prothrombin time (PT) and activated partial throm-boplastin time (APTT) assay, and it was observed that biologically reduced nanodiamonds have potent an-tiplatelet activity. © 2021 Sumy State University

Аннотация: Recombinant apoobelin and recombinant luciferase are separated from bacterial cells of Escherichia coli with the use of detonation nanodiamonds. The application of nanodiamonds has a number of points in its favor, namely, (i) simplifies the procedures for purifying the proteins, (ii) decreases the time of their separation to 30-40 min, (iii) eliminates the necessity of using special chromatographic equipment, and (iv) makes it possible to prepare high-purity apoobelin and luciferase materials with protein yields of 35-45 and 45-60%, respectively. The possible mechanisms of interaction of protein molecules and nanodiamond particles are analyzed. (C) 2004 MAIK "Nauka / Interperiodica".

Аннотация: In vitro experiments proved the usefulness of electron paramagnetic resonance (EPR) spectrometry for detecting detonation nanodiamonds (NDs) in samples of biomaterials (blood and homogenates of organs of mice). A characteristic EPR signal (g = 2.003, Delta H similar or equal to 10 G) was detected in biomaterials containing NDs, and its intensity linearly increased at nanoparticle concentrations of between 1.6 and 200 mu g/ml. In vivo experiments demonstrated that EPR spectrometry was effective for monitoring the inter-organ distribution of NDs intravenously injected to mice. In 2.5 h after the injection of NDs, the nanoparticles mainly accumulated in the lungs and liver of the animals - about 25 and 20%, respectively, of the initially injected NDs. The amounts of NDs accumulated in the heart and kidneys were considerably lower. Also, EPR spectrometry did not detect NDs in the blood, spleen, brain, and femoral muscles of mice. Ten days after injection, EPR spectrometry detected redistribution of NDs in mice. The amounts of nanoparticles decreased approximately by a factor of 3.5 in the lungs and increased almost by a factor of 3 in the liver; NDs were detected in the spleen. This study suggests ways to use EPR spectrometry to study the distribution, accumulation, and elimination of detonation NDs injected into laboratory animals.

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.

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: In experiments in vitro on human blood, it was shown that nanodianiond (ND) particles change the kinetics of active oxygen generation (AOG), causing white cell destruction and erythrocyte hemolysis. Various mechanisms of the observed effects have been considered. Nanodianionds adapted for biological research and possessing higher colloidal stability make it possible to obtain sterile hydrosols and mixtures with drugs and are more preferable for medical -biological research. We discussed the necessity of experiments in vivo and showed the first results of injection of the adapted nanodianionds to the laboratory animals. (C) 2004 Elsevier B.V. All rights reserved.

Detection of nanodiamonds in biological samples by EPR spectrometry / E. V. Inzhevatkin [et al.] // Doklad. Biochem. Biophys. - 2017. - Vol. 477, Is. 1. - P394-397, DOI 10.1134/S1607672917060138 . - ISSN 1607-6729
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.

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: The effect of laser radiation polarization on the nonlinear scattering of light in aqueous suspensions of detonation nanodiamonds (DNDs) in a regime of optical power limiting (OPL) has been studied. It is established that the nonlinear transmission coefficient of DND suspension in the OPL regime in a field of nanosecond laser pulses with a wavelength of 532 nm is independent of the polarization of incident radiation. The nonlinear scattering of light observed at an angle of 90A degrees in the plane perpendicular to the plane of polarization of the incident radiation depends on the polarization angle in accordance with a trigonometric law. It is shown that the ratio of the signals of scattered radiation for the vertical and horizontal polarizations exhibits nonmonotonic dependence on the laser-beam power density. The results are explained by the Rayleigh-Mie scattering and a change in the size of scattering centers as a result of the effect of a laser upon the DND suspension.

Аннотация: Experiments in vivo demonstrated the protective effect of modified nanodiamonds on guinea pig skin after local exposure cobalt ions, but not chrome ions. The observed differences are determined by different adsorption of these ions by nanodiamonds: in vitro experiments showed that nanodiamonds adsorbed cobalt ions, but not chrome ions from water solutions. The perspectives of using modified nanodiamonds as a new adsorbent for prevention of allergic contact dermatitis induced by ions of bivalent metals are discussed. © 2014, Springer Science+Business Media New York.

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.
