| Annotation: | The topic of submitted project reflects current scientific challenges using the strategy of an interdisciplinary approach in tackling the highly urgent issues of microbial biofilms. It is focused on the fields of basic and molecular microbiology in association with study of the prevention or eradication of microbial biofilms using novel hybrid materials. In the project, biological research is closely linked to various approaches in the field of the nanomaterial chemistry. The main subject of the study will cover multispecies biofilms, not only composed of bacteria but also of yeasts and their mutual combinations, which reflects their significance in biofilm-associated infections. The tested microorganisms will include Staphylococcus aureus, enterococci, Escherichia coli, and representatives of yeasts of the genus Candida. The formation of biofilms, interspecies interactions, including the role of quorum sensing molecules in these processes, as well as the effectiveness of bioactive particles/molecules in the prevention and eradication of biofilms, including the phenomenon of multidrug resistance, will be studied in detail by modern microbiological methods. Hybrid materials based on inorganic layered nanoparticles in the role of carriers of bioactive organic molecules, in particular photosensitizers, will be used as active materials. Functionalized nanoparticles will be used to modify the surfaces of selected types of polymers often used in medical practice. The aim will be to prepare new or improved materials to achieve maximal antimicrobial effectiveness. The results of the project could bring new knowledge in the topic of microbial biofilms, but also in the preparation of antimicrobial hybrid systems applicable in various fields of nanomedicine. |
