The food processing industry faces the major challenge of ensuring optimal surface hygiene while simultaneously improving process efficiency. The OREGANO project aims to create innovative metallic surfaces with a dual antimicrobial effect. This effect is achieved through the covalent grafting of arylbenzothiazole derivatives with biocidal properties, and through surface microstructuring that prevents the formation of bacterial biofilms. The project comprises several components: synthesis of new compounds, evaluation of their antimicrobial properties (using in vitro and in silico approaches) and cytotoxicity, grafting (chemically or electrochemically) onto surfaces, and inkjet printing technologies for microstucturation.
