Within the framework of the project fundamental nature studies will be carried out, which will ensure the creation of a biosensor based on ZnO nanostructures, which will be able to identify the DNA of a specific biological object in a sample of complex nature. The results of the research will be concentrated in the prototype of the device, which will provide the necessary properties for modern requirements – the analysis can be carried out quickly, with great reliability, the equipment is compact and portable. The study consists of several phases: Synthesis of ZnO nanostructures of optimal morphology using gaseous, hydrothermal and electrochemical synthesis methods; Research on the properties of the resulting nanostructures (crystalline structure, electrical, optical, photovoltaic, surface wetting, etc.); Study of immobilisation processes of DNA molecules on the surface of bioelectrous and signal identification from complementary and non-complementary DNA chains using impedance spectroscopy, conductometry, combined light dissipation, plasma resonance imaging; Exploring the potential to increase the sensitivity of the biosensor (e.g. sophistication of ZnO nanostructures with various metals or their oxides, surface coating with nanoparticles, etc.); Production of a prototype measuring device. Within the framework of the project it is planned to: Publish at least four scientific publications in existing scientific journals of Web of Science and/or SCOPUS databases with impact factor above the industry average. Biosensor, ZnO nanostructures, DNA sensor.Project objective: Develop a biosensor-based device for detecting the presence of DNA in a specific biological object in a sample. The project will be in line with the fields of science: 1.6. Biological sciences, 2.5. Materials engineering, 2.10 – nanotechnologies, it is unrelated to economic activity. Within the framework of the project, a biosensor based on ZnO nanostructures will be created, which will be able to detect the DNA of a specific biological object in a sample of complex nature. The results of the research will be concentrated in the prototype of the device, which will provide the necessary properties for modern requirements – the analysis can be carried out quickly, with great reliability, the equipment is compact and portable. Within the framework of the project it is planned to: Publish at least four scientific publications in existing scientific journals of Web of Science and/or SCOPUS databases with an impact factor above the industry average; Make one prototype of the equipment, perform the appropriate measurements and sample synthesis.Total project costs: EUR 600000, ERDF contribution – EUR 510000. Duration of project implementation: 36 months, expected implementation period from 01.03.2017 to 29.02.2020.
