Search and investigation for novel two-dimensional materials for biochemical sensing applications.

As the most of the two-dimensional crystals that can be obtained from natural crystalline materials with layered structures (graphene, TMDC and so on) have already been subjected to a comprehensive studies of their inherent properties, the focus of scientific interest in the field is increasingly extending to include the unique artificial two-dimensional materials: materials possible to synthesis only under laboratory conditions... Theoretical approaches to the prediction of novel materials can significantly reduce the time spent on experimental synthesis and research on promising for use in electronics, catalysis, and sensors two-dimensional materials. In particular, the high surface area and variability of chemical compositions of two-dimensional transition metal chalcogenide nanostructures can be used for a wide range of applications, specifically for biological molecule detectors. The goal of the project is to search for novel two-dimensional structures of binary composition representing non-stoichiometric phases of metal chalcogenides Mo, W, V, Pt, Ru, Ti and study their electronic properties under the influence of adsorbed groups of biological molecules. This will allow offering novel materials that are promising for highly sensitive sensors of biomolecules and gases.
