Nanomaterials as ecotoxicants and promising medical materials
Due to surface and quantum-dimensional effects, nanoscale materials have special structural, physicochemical, electrical and optical properties, which determines their effective use in most modern high-tech processes not only in the field of electronics, optoelectronics, laser technology, but also in biomedical, food and cosmetic technologies. Therefore, it is important to determine the mechanisms of action of nanomaterials in the event of their acute, short-term, subchronic intake into the body using the methods of physiology, biochemistry and cell biology. The research group of the Department of Molecular Biotechnology and Bioinformatics is carrying out a comprehensive study of the molecular and cellular mechanisms of functioning of visceral smooth muscles (in particular, stomach, large intestine and uterus) and liver under conditions of in vitro and in vivo exposure to nanomaterials (with different duration of intake). So far, the mechanisms of action of TiO2 and ZnO nanoparticles have been analysed in detail. It is planned to study the patterns of accumulation in tissues and the mechanisms of influence of noble metal nanoparticles on the state of the hepatobiliary system and the functioning of visceral smooth muscles.
