Advancing surface safety: the role of sol-gel nanocoatings in the context of MIRIA European project

Abstract

Among the challenges posed by the COVID-19 pandemic, significant efforts have been undertaken to develop antimicrobial/antiviral surfaces by exploiting coating solutions. In this article, we review the actions undertaken by the EU project MIRIA, the main one being the reduction of pathogen transmission on high-traffic surfaces in public and healthcare environments. The project implements several synergies from key antimicrobial/antiviral element selection to the grafting of complex-shaped surfaces. The focus is given to one of the project’s key strategies: the adoption of sol-gel technology, known for its efficiency in creating versatile, cost-effective coatings suitable for a wide range of substrates. The project rigorously tests the coatings in simulated environments, such as operating theatres, ensuring their effectiveness and safety. This includes comprehensive durability testing against environmental, chemical, and mechanical stresses, guaranteeing the coatings’ long-term functionality. MIRIA’s validation process encompasses antibacterial, antifungal, and antiviral testing in line with international standards, confirming their broad-spectrum pathogen resistance. Along with this overview, the impact of the initiative is elucidated, extending beyond healthcare, enhancing public health, creating safer living, and working environments, and reducing economic losses due to illness. To this, the MIRIA project is expected to significantly contribute to the European research and innovation in antimicrobial coatings, addressing challenges like scalability and efficacy against various pathogens. The emphasis on sustainable synthesis, including bio-based materials which align with ecological goals, positions MIRIA as a pivotal initiative in enhancing health safety standards and resilience across Europe.
