Ana Iglesias JuezThe increased microbial resistance to common disinfectants and antibiotics leads to the fact that infection by pathogenic microbe remains one of the most common causes of death. World Helth Organization (WHO) also indicates that governments should raise food safety to the public health priority range. Many foodborne diseases are caused during processing, manufacturing and preparation of foods. Antimicrobial coating of work surfaces and used utensils is an effective way to contribute to food safety. Therefore, the development of new, more effective biotechnological disinfection systems is crucial. However, the knowledge about the action mechanisms, especially in fungicide treatments, is still very limited. For this reason, it is necessary to study new systems and in greater depth the microbial degradation routes in order to improve their efficiency in the biotechnological processes of surface disinfection. This project focuses on the development of novel nanometric antimicrobial agents. The main objective of this project is to provide new biotechnological tools that are founded on multifunctional photocatalytic systems based on transition metals nanoparticles, mainly Cu, supported on modified ZnO nanostructures and/or supported on graphene derivatives that possess improved biocidal properties for their application in antimicrobials coatings and thus increase hygiene on work surfaces and prevent the spread of unwanted microorganisms. This project involves a multidisciplinary approach that combines several techniques of analysis and where the scientific training of the different members is the key to solve the search for cost-effective and safer nanotechnologies that prevent biological risk in a wide range of applications.
