Areas of Scientific Activity
Vibrational spectroscopy of molecules at a metal surface – surface enhanced Raman scattering (SERS), surface enhanced resonance Raman scattering (SERRS), tip-enhanced Raman scattering (TERS). Structure of self-assembled monolayers of organic compounds on metal surfaces. Shape-controlled metal nanoparticles for construction of the SERS – based Raman sensors.
Protein misfolding and formation of amyloid fibrils. Biophysical studies on stability and dynamics of protein aggregates (using FT-IR, Raman, CD, VCD, ROA, fluorescence spectroscopy and AFM/TEM/SEM). Life under extreme conditions: protein folding and unfolding under high pressure and conformational transitions of biopolymers in unbiological environments. Applications of proteins and polypeptides in nanotechnology.
Methodological aspects of NMR spectroscopy. The development of new approaches for acquisition of multidimensional NMR spectra. The application of Multiple Fourier Transformation to nonlinearly sampled NMR data sets.
Catalytic properties of various core-shell metal nano-clusters. Plasmon-driven synthesis of metal nano-structures. Recording and analysis of surface-enhanced Raman scattering (SERS) spectra dominated by the contribution from only a few molecules.
Ab initio calculations of Nuclear Magnetic Resonance parameters (spin-spin coupling constants and NMR shielding constants), of spectroscopic properties associated with chirality (optical rotation, Electronic Circular Dichroism spectra, Raman Optical Activity Spectra). Relativistic effects on NMR parameters.
Theoretical calculations for molecules and their complexes. Modeling of intermolecular interactions of the molecular complexes. Molecular spectra (IR, NMR, VCD) of interacting molecules. Hydrogen bonds and dihydrogen bonds. Chirality transfer. Relativistic effect on NMR parameters.
