As a result of the implementation of the project, various types of tumor cell cultures will be analyzed, as well as sections of pathological tissues - tumor tissues of various degrees of malignancy and different localization, dura mater tissues after craniocerebral trauma before and after the use of therapeutic procedures. The research methodology is based on a complementary multidisciplinary approach using experimental methods (optical and vibrational spectroscopy, electron, atomic force and confocal microscopy) and computer modeling (quantum-chemical and molecular-dynamic calculations, molecular docking). It is planned to investigate the influence of various drugs (antiviral, antitumor, thrombolytic drugs), as well as the latest methods of treatment on the structure and morphological features of the studied objects in order to identify patterns and physical mechanisms of such interactions, to improve the methods of their experimental study, to propose new computational algorithms and methods data analysis during their in silico study. Understanding the peculiarities of the structure and dynamic behavior of biological molecules and systems during their interaction with small molecules, nanoscale and supramolecular complexes will have fundamental scientific importance for molecular biophysics, will open the way for a directed influence on their functionally important properties for the further creation of artificial nano and other devices for use in various spheres of life popup.nrat_date 2024-12-09 Close
