Microplastic content variation in water column: The observations employing a novel sampling tool in stratified Baltic Sea
(2019) Marine Pollution Bulletin, 138, pp. 193-205.
КРАТКОЕ ОПИСАНИЕ: A new tool was developed for microplastics (MPs) investigation in the water column. It can collect several cubic meters of water from predefined water layers down to 100 m. The tool was tested in the Baltic Sea during the period of spring thermocline formation. Strong MPs stratification was observed at all of the sampled stations. On coastal stations (~30 m deep), stratification with high fibers content was associated with the proximity of terrestrial sources and estuarine discharges, while on off-shore stations the variability of MPs was related to vertical thermohaline structure. Mean MPs content was the 32.2 (SD 50.4) pcs/m3. Elevated MPs concentrations were observed in subsurface, near-bottom and thermohaline layers compared with intermediate layers. The heterogeneity of MPs distribution suggests that MPs particles can be retained above the density-gradient layers in coastal seas and the World Ocean.

КРАТКОЕ ОПИСАНИЕ: Double-pulse laser excitation of the eosin and silver nanoparticles embedded into polymer media is known to be a method of electronic-vibrational energy deactivation kinetic process information obtaining and polymer thermal dynamics investigation. We have studied the vibrational relaxation processes in dye molecules (eosin) and nanoparticles in polyvinyl alcohol after two time-shifted laser pulses with fast and delayed fluorescence kinetics study. In order to simulate thermal and photophysical processes caused by double photon excitation, we solved heat transfer and energy deactivation differential equations numerically. The simulation allowed us to obtain the value of heat conductivity coefficient of polymer matrix.

Effect of plasmonic interaction between rhodamine 6G in polyvinyl alcohol film and rough silver surface: Estimation of absorption energy to plasmon excitation
(2018) Proceedings of SPIE - The International Society for Optical Engineering, 10672, статья № 1067230.
КРАТКОЕ ОПИСАНИЕ: The optical processes of plasmonic enhancement of rhodamine 6G molecules fluorescence in dielectric films of polyvinyl alcohol deposited on a rough silver surface have been studied. The reflection coefficients of the polarized light components on rough silver surfaces have been determined by means of spectral ellipsometry and spectrophotometry methods. Two kinds of silver surfaces were used: without and with anodizing at current density of 5 mA/cm2 of 0.5 μm layer. The plasmon spectrum appeared to be red-shifted after polyvinyl film deposition onto the silver plate. I was shown that the silver-dielectric interface roughness affects the position of the reflected light spectrum maximum to 360 - 400 nm range due to the dielectric polarizing effect.

Refraction, fluorescence, and Raman spectroscopy of normal and glycated hemoglobin
(2018) Proceedings of SPIE - The International Society for Optical Engineering, 10685, статья № 1068540.
КРАТКОЕ ОПИСАНИЕ: In this study, the optical properties of glycated (HbA1c) and non-glycated (Hb) hemoglobin are compared using refractometry, fluorescence and Raman spectroscopy. The fluorescence measured at an excitation wavelength of 270 nm indicates differences in the molecular structure of hemoglobins. Analysis of the spectral shift of Raman spectra also showed variations indicating differences in their molecular structure. The refractive index measured in the visible and near IR regions for different temperatures allowed for quantification of mean values of temperature increment, which are quite different as dn/dT= -(1.03 ± 0.05)×10-4°C-1 for Hb and - (1.37 ± 0.07)×10-4°C-1for HbA1c.The data obtained in the work can serve as a basis for further study of the optical properties of glycated hemoglobin and other glycated proteins.

(2018) Laser Physics, 28 (4), статья № 045403.
КРАТКОЕ ОПИСАНИЕ: An analytic and numerical study is carried out of the dynamics of parameters of a super-Gaussian pulse whose spectrum can fit both in the region of normal and anomalous dispersion of the group velocity. An analytical solution is found for the parameter characterizing the evolution of the degree of the super-Gaussian momentum. The loss of profile rectangularity is shown to be much faster than the pulse dispersion broadening, and corresponding characteristic length is determined by explicit formula.

Simulation of Raman scattering including detector parameters and sampling volume
(2017) Journal of the Optical Society of America A: Optics and Image Science, and Vision, 34 (12), pp. 2138-2144.
КРАТКОЕ ОПИСАНИЕ: Raman spectroscopy can be employed to measure the chemical composition of a sample, which can in turn be used to extract biological information. The aim of this paper is to introduce an efficient simulation technique for Raman spectroscopy in turbid (scattering) media taking into account relevant detector parameters and the sampling volume. We simulate the process of photon motion in turbid media by means of the Monte Carlo (MC) method. The numerical simulation of Raman scattering consists of two stages: calculation of the photon fluence at each point of the medium and subsequent generation of the corresponding amount of Raman photons at each point. The developed model allows simulation of both confocal and optical fiber probe Raman setups. In more detail, the model efficiently simulates Raman signals for different single and multi-layer phantoms and geometries, including focused and collimated (i.e., the fiber-based case) excitation laser beams as well as different values for the numerical aperture and the excitation beam radius. In the future, our results offer the potential to improve the design of Raman systems for in vivo applications in biomedical research.

Ordinary differential equations and boolean networks in application to modelling of 6-mercaptopurine metabolism
(2017) Royal Society Open Science, 4 (4).
КРАТКОЕ ОПИСАНИЕ: We consider two approaches to modelling the cell metabolism of 6-mercaptopurine, one of the important chemotherapy drugs used for treating acute lymphocytic leukaemia: kinetic ordinary differential equations, and Boolean networks supplied with one controlling node, which takes continual values. We analyse their interplay with respect to taking into account ATP concentration as a key parameter of switching between different pathways. It is shown that the Boolean networks, which allow avoiding the complexity of general kinetic modelling, preserve the possibility of reproducing the principal switching mechanism.

ATP concentration as possible marker of liver damage at leukaemia treatment: Confocal microscopy-based experimental study and numerical simulations
(2017) Proceedings of SPIE - The International Society for Optical Engineering, 10337, статья № 103371B.
КРАТКОЕ ОПИСАНИЕ: We consider the method of confocal microscopy as a convenient instrument for determination of chemical compounds in biological tissues and cells. In particular, we study the dynamics of adenosine triphosphate (ATP) concentration that could be used as a bio-marker of energy metabolism pathologies at the treatment of acute lymphoblastic leukaemia (ALL). On the basis of data obtained by the confocal microscopy, the values of ATP concentration have been calculated for each case. Possible correlations with other characteristics of pathology processes obtained from plasma of leukemia patients show that ATP value could be a prognostic factor of the treatment success. The role of ATP in the drug metabolism switching is also discussed within the context of kinetic modelling of metabolism processes leading to the production of 6-Thioguanosine monophosphate, which is a principal acting agent in chemotherapy.

(2017) Proceedings of SPIE - The International Society for Optical Engineering, 10456, статья № 104563E.
КРАТКОЕ ОПИСАНИЕ: We have been searching for new photosensitizers (PS) for photodynamic therapy (PDT) of cancer based on extracts from Amazonian plants since 2009. In this paper, we demonstrate that, under certain conditions, the extract from fruits of the Amazonian palm Euterpe oleraceae (popular name Açaí) can serve as a PS for PDT treatment of murine breast cancer cells (4T1 cell line). We have been first to show directly that the photodynamic effect of plant PS is due to singlet oxygen.

Analytic description of Raman-induced frequency shift in the case of non-soliton ultrashort pulses
(2017) Physics Letters, Section A: General, Atomic and Solid State Physics, 381 (4), pp. 399-403.
КРАТКОЕ ОПИСАНИЕ: Raman-induced frequency shift of ultrashort pulses have been studied extensively for the soliton propagation regime. Here we derive explicit analytic expressions for the evolution of Raman-induced frequency shift in much less studied case of non-soliton ultrashort pulses. Pulse spectra may belong to any region of group velocity dispersion including zero group dispersion point. The analysis is based on the moment method. Obtained expressions fit well to the numerical solution of the nonlinear wave equation.

(2016) Proceedings of SPIE - The International Society for Optical Engineering, 10024, статья № 1002432.
КРАТКОЕ ОПИСАНИЕ: The treatment of acute lymphoblastic leukemia (ALL) can result in the side-effects such as kidney affection, hepatic failure and tissue hypoxia. We study dynamics of special biochemical marker of these pathologies - adenosine triphosphate, that is well-known substance of energy metabolism. We use methods of confocal microscopy for determining the cellular and mitochondrial concentration of adenosine triphosphate (ATP). Quantitative values of adenosine triphosphate were calculated for each patient and correlation with degree of side-effects had been done. The application of confocal microscopy for studying of side-effects and therapy of lymphoblastic leukemia is discussed.

КРАТКОЕ ОПИСАНИЕ: We use spectral kinetic methods to study electronic energy transfer processes between semiconductor quantum dots on the surface of wide-pore silica in the absence of and in the presence of silver nanoparticles, obtained by laser ablation methods. We have determined the efficiencies of dipole–dipole energy transfer between two-shell (CdSe/CdS/ZnS) and one-shell (CdSe/ZnS) quantum dots on the surface, the luminescence lifetimes and quantum yields, transfer distances and transfer rate constants. We have studied enhancement of photoprocesses in individual quantum dots and in a pair under the influence of resonant localized plasmons of ablative silver nanoparticles.

КРАТКОЕ ОПИСАНИЕ: The plasmonic enhancement and quenching of phosphorescence and fluorescence of the anionic (eosin) and cationic (rhodamine 6G) dyes have been studied in various environments: silver nanoparticles of silver hydrosol citrate in water, in polymer films and on the surface of nanoporous silica in order to determine the kinetic and spectral effects on the dye luminescence. Depending on the silver nanoparticles concentration both the enhancement and quenching of the dyes phosphorescence and fluorescence have been detected. The mechanism of interaction between the excited molecules and silver nanoparticles has been discussed.

Delayed luminescence of erythrosine in biological tissue and photodynamic therapy dosimetry
(2016) Journal of Photochemistry and Photobiology B: Biology, 163, pp. 232-236.
КРАТКОЕ ОПИСАНИЕ: The features of delayed fluorescence (DF) and phosphorescence in erythrosine stained healthy and cancer-diseased mammary gland tissues of BYRB-line mice were investigated in vitro. Thermoactivated delayed fluorescence (TDF), triplet-triplet annihilation (TTA) and originated from singlet-triplet annihilation (STA) delayed fluorescence are investigated as competing channels of radiative relaxation of the triplet states of erythrosine. The dominant role of diffusive-mobile molecular oxygen in deactivation of triplet-excited long-live states of the dye molecules in cells is determined. The previously not described phenomenon of light quenching of DF under pulsed laser irradiation (light quenching of DF, LQDF) in stained tissue was revealed. LQDF is increased if the energy of excited pulses is rise and their sequence period is decreased. The DF depletion disappears if time interval between pulses in the series is > 5 s. This phenomenon is due two process competition: fast consumption of singlet oxygen by oxidation of cell organelles right after laser pulse excitation and slow diffusive recovery of oxygen concentration in the pause between the pulses. Statistically valid distinction between DF characterization as well as LQDF erythrosine extent in healthy and pathological tissues was established. The use of this phenomenon will greatly simplify the determination of radiation “dose” in photodynamic therapy (PDT) directly during the treatment session.

Temporal compression of pulses from a 100-kHz-repetiton-rate femtosecond ytterbium laser
(2016) Quantum Electronics, 46 (8), pp. 675-678.
КРАТКОЕ ОПИСАНИЕ: We report the temporal compression a femtosecond ytterbium laser pulse at a pulse repetition rate of 100 kHz using the effect of nonlinear self-phase modulation in a gas-filled capillary. A 260-fs laser pulse is compressed down to 17 fs with an energy efficiency of 40%. An average radiation power at the compressor output is 2 W. At a second compression stage, the time contrast is increased and the pulse duration is reduced in the process of the second harmonic generation in a KDP crystal. The obtained pulses have a duration of 11 fs at an efficiency of 35%.

(2015) Quantum Electronics, 45 (10), pp. 908-913.
КРАТКОЕ ОПИСАНИЕ: The fluorescence and phosphorescence of dyes in thin polymethylmethacrylate (PMMA) films in the presence of ablated silver nanoparticles has been investigated in a wide temperature range by methods of femtosecond and picosecond laser photoexcitation. The fluorescence and phosphorescence times, as well as spectral and kinetic characteristics of rhodamine 6G (R6G) molecules in PMMA films are measured in a temperature range of 80 - 330 K. The temperature quenching activation energy of the fluorescence of R6G molecules in the presence of ablated silver nanoparticles is found. The vibrational relaxation rate of R6G in PMMA films is estimated, the efficiency of the dipole - dipole electron energy transfer between R6G and brilliant green molecules (enhanced by plasmonic interaction with ablated silver nanoparticles) is analysed, and the constants of this energy transfer are determined.

The effect of gold nanoparticles on exchange processes in collision complexes of triplet and singlet oxygen molecules with excited eosin molecules
(2015) Optics and Spectroscopy (English translation of Optika i Spektroskopiya), 119 (1), pp. 29-38.
КРАТКОЕ ОПИСАНИЕ: We have studied exchange processes in contact complexes of triplet eosin molecules with oxygen molecules in the triplet (3Σg−) and singlet (1Δg) states in thin polyvinylbutyral films in the presence of gold nanoparticles. Upon resonant excitation of surface plasmons in gold nanoparticles into the absorption band of eosin molecules-singlet oxygen sensitizers-we have obtained an increase in the intensity of the delayed fluorescence and an increase in the lifetime of the dye with simultaneous quenching of the luminescence of singlet oxygen. The kinetics of the delayed fluorescence of the dye as a result of singlet-triplet annihilation of triplet eosin molecules with singlet oxygen molecules has been investigated. To compare theoretical and experimental data, we have numerically simulated energy transfer processes. Rate constants of energy transfer and of singlet-triplet annihilation, as well as quenching constants of triplet states of the dye by molecular oxygen, have been calculated. Luminescence quantum yield 1Δg of polyvinylbutyral has been estimated. We have analyzed quantum-chemically electronic mechanisms of singlet-triplet annihilation of oxygen and eosin.
