Scientific interests and research areas

Scientific interests and research areas

The interests of our group are primarily in assembly of supramolecular complexes with DNA and their structural-functional characterization for elucidation of native regulatory processes and for development of nucleic acid-based diagnostic/therapeutic agents and various functional nanoconstructs.

Our recent studies focus on 3D dynamics of polynucleotides and their supramolecular complexes and on regulatory roles of noncanonical DNA structures (ncDNA). We investigate sensitivity of DNA secondary/tertiary structures to external stimuli and its implications for adaptive processes.

Our major research activities

  • Design and assembly of nucleoprotein complexes for targeted drug delivery.
  • Development of DNA-based tools that modulate properties of biosystems, biosensors and tools for cell manipulation and tissue engineering.
  • Assembly of nanoparticles functionalized with DNA and nucleoprotein complexes.
  • Investigation of DNA conformational dynamics with respect to genomic regulation and analysis of structure, thermodynamics and kinetics of complex formation between ncDNA/RNA/epigenetically modified ncDNA sites (formed upon recombination, transcription or reparation) and proteins (transcription factors, chromatin remodeling factors and others) or between ncDNA/RNA and small molecules (native and synthetic ligands to G4/IM structures) – potential drugs.
