Main Scientific Directions of the Group

Group of laser spectroscopy of solutions of supramolecular compounds and nanostructures is very young. We have grown up in the laboratory of laser spectroscopy of water media. Our history begins since September 2008. Scientific themes of the group include the following main directions.

Study of solutions of supramolecular compounds

Creation of new well-ordered supramolecular materials with given structure and properties plays an important role in processes of creation of new nanocomposites, films, membranes, in nanobiotechnologies and nanomedicine. Because amphiphilic compounds (containing hydrophilic and hydrophobic groups) are the base of supramolecular compounds, it is very important to study processes of formation of clathrates, self-organization, creation of micellar systems in water-ethanol solutions, surface active compounds, polymers etc.

One of our new problems is from the domain of energetics of biologic membranes: study of solvate and energetic properties of lipophylic cations, which can selectively penetrate membranes and deliver antioxidants into mitochondria of cells. Study of molecular interactions of such ions in water and bioobjects open fundamentally new opportunities of creating drug products and solving gerontology problems at the cell level. In our group, these studies are carried out using methods of vibrational spectroscopy (spectroscopy of infrared (IR) absorption and Raman spectroscopy) combined with correlation spectroscopy (Chair of Physics of Polymers and Crystals, Physcial Department of Moscow State University), potentiometry (Department of Bioengineering and Bioinformatics, A.N.Belozersky Research Institute of Physico-Chemical Biology, Moscow State University), methods of molecular dynamics (A.N.Frumkin Institute of Physical Chemistry and Electrochemistry).

Penetration of lipophylic cations into a cell

Study of properties of nanoparticles and nanocomposites in liquid media

Objects of our investigations belong to a principally new class of composite materials that have emerged due to latest achievements in synthesis, bioadaptation and bioconjugation of nanoparticles. These are colloidal solutions of fluorescing nanoparticles (nanodiamonds (ND), carbon quantum dots (CQD)). These objects are of interest both from fundamental and practical points of view. Unique fluorescent properties of carbon quantum dots and nanodiamonds, their safety and non-toxicity allow their active use as optical biosensors. Due to developed multifunctional surface of ND and possibility of its modification this material has a very promising perspective for wide application in biology and medicine for adsorption and targeted drug delivery as well.

Multi-functional surface of nanodiamond

Thereby it is very topical to study molecular interactions and optical properties of nanoparticles in solutions, to search for approaches to manage these properties, including modification of surface functional groups or creation of new nanocomposites based on nanoparticles. Thus, optimization of properties of nanoparticles in the solutions for getting maximal therapeutic effect is impossible without solution of fundamental problems - study of mutual influence of matrix-solvent and nanoparticles on their optical, adsorption, vibrational properties. Such studies of molecular interactions of surface functional groups of initial and modified nanoparticles in solutions are carried out in our laboratory together with partners from GPI RAS, chemists from Turku University, technologists from USA.

Methods of artificial intelligence in optical spectroscopy

For precision analysis of vibrational spectra of studied solutions and to solve multi-parametrical inverse problems of vibrational spectroscopy we use artificial neural networks and genetic algorithms. Use of such powerful modern tools of solution of inverse problems and problems of optimization provides successful solution of a wide range of applied problems of diagnostics and analysis of water media.

Fundamental problems

Important information about intra- and intermolecular interactions in water can be obtained from spectroscopic characteristics of water, in particular, from the spectra of water Raman scattering. Until now, the structure of liquid water is not clear, and no complete model of vibrational processes in liquid water, which could adequately explain mechanisms of formation of water Raman spectral bands, has been established. Besides that, there are serious contradictions in conceptions about resonance interactions of vibrations in water molecules. The problem of contribution of Fermi resonance (resonance between overtone of bending vibrations and symmetric valence vibrations) to formation of valence band of water Raman spectrum still remains topical.

Water Raman spectrum is rather complicated, and it consists of a number of bands with different intensities, widths, and shapes. Its typical appearance is displayed at the diagram below.

Water Raman spectrum

50~200 cm^-1 - bands of intermolecular translational vibrations with maxima at about 60 and 190 cm^-1;
300~900 cm^-1 - band of intermolecular librations with maximum at about 700 cm^-1;
1600~1700 cm^-1 - bending band with maximum at about 1645 cm^-1;
2000~2400 cm^-1 - associative band with maximum at about 2200 cm^-1; probably caused by overtones of intermolecular vibrations and by combinational frequences;
3000~3800 cm^-1 - valence band with maximum at about 3400 cm^-1;
3900~4200 cm^-1 - weak intensity band with maximum at about 4000 cm^-1; probably caused by overtones of intermolecular vibrations and by combinational frequencies;
6000~7000 cm^-1 - weak intensity band, probably an overtone of the valence band.

It is very difficult to get information directly from the spectrum because many of these bands are weak and have nearly no internal structure. That is why it is very important to study changes of Raman spectra under influence of various factors (for example, dissolved compounds or temperature). Under influence of dissolved substances and change of temperature hydrogen bonds in water and configuration of water clusters change and it reveals in Raman spectra.

Experimental data about weak bands of water Raman spectrum is very contradictory. These bands can be studied only using ultra-high sensitive detectors (CCD and photomultipliers with photon counting systems). Behaviour of most intensive valence band was studied in detail, but obviously the whole picture of vibration processes in water can be presented only when all of Raman bands are studied. Up until now there were few publications with results of research of some water Raman bands simultaneously (usually no more than two). Mechanisms of intra- and intermolecular interactions are formed in different ways and that is why they can be clarified only in case all Raman bands are studied simultaneously.

We pay special attention the research of weak bands of water Raman spectrum. These bands are caused by resonance vibrational interactions of water molecules and combination frequencies. Especially the role of Fermi resonance in formation of water Raman valence band and spectral band at 6000-7000 cm^-1 are studied.

We also study intra- and intermolecular interactions in water, mechanisms of formation of water vibrational bands and structural peculiarities of water. This is achieved through studying of changes of water Raman spectrum under influence of the following factors: temperature, dissolved compounds.

Influence of the temperature

Study of Raman bands of water at different phases: ice (-50~0 њC); supercooled water (-25~0 њC); liquid water (0~100 њC) and (as planned) vapor (over 100 њC). Under increase of the temperature hydrogen bonds weaken, water clusters change and it is revealed in Raman spectra.

Various dissolved compounds

Study of behaviour of water Raman spectra in the solutions of various compounds.

Solutions (Н₂О+D₂О) in different ratio
These solutions are interesting because at dilution D₂О in Н₂О number and orientation of intra- and intermolecular bonds do not change (deuterium atoms just replace hydrogen atoms). But forces of intramolecular, deuterium and hydrogen bonds change and it reveals in Raman spectra.

Solutions of inorganic salts, acids, alkalis in the full range of their solubility
Molecules of inorganic compounds dissociate in water and ions are surrounded by hydrate shells. In dependence on properties of ions their hydration happens in different ways. Revelation of hydration properties in Raman bands is studied, as well as formation of ion pairs, proton migration in water.

Solutions of organic compounds
Studied is the revelation of interactions of water molecules with hydrophilic and hydrophobic organic compounds in low frequency bands of water Raman spectra and in Raman spectra of these compounds.

Applied science

Results of study of influence of temperature and various admixtures on valence band of water Raman spectra are used for solution of inverse problems of Raman spectroscopy - development of remote methods of simultaneous determination of temperature, salinity of water and concentration of inorganic and organic compounds in water media including natural waters.

We have developed a method of simultaneous determination of water temperature and salinity (i. e. determination of total concentration of salts in seawater). Inverse three-parametrical problem - identification of the salts and determination of their partial concentrations in three-component solutions - was solved.

Novel methods of solution of inverse problems are used throughout our research - artificial neural networks, genetic algorithms, group method of data handling.
