Healthcare-related infections (HAIs) are a huge global issue. In 2020, about 11,124 patients (12.7%) with an ICU (intensive care unit) stay of over two days developed at least one ICU-acquired healthcare-associated infection (European Centre for Disease Prevention and Control, 2024). Hospital-acquired infections are mainly caused by contamination of these facilities, which often involves the transmission of microorganisms through contact with contaminated surfaces. In this context, the advancement of novel strategies to mitigate the contamination of medical devices, biomaterials, and hospital equipment is crucial and drives the demand for advancements in materials sciences. The application of antimicrobial polymers to coat medical devices and other hospital equipment has emerged as a promising approach, reducing the risk of healthcare-related contamination. The main goal of this research was to incorporate silver nanoparticles (Ag-NPs) into a waterborne castor oil-based polyurethane (PU) suspension to produce a film coating and evaluate its effectiveness in preventing bacterial adhesion. The films of pristine polyurethane (WBPU) and polyurethane containing Ag-NPs were subjected to physicochemical characterization and antimicrobial assays. Thermogravimetric analysis showed that no decomposition occurs below 200 oC, and the PU can be used in materials at the body temperature range. The WBPU film with 0.4% (w/w) Ag-NPs exhibited 36.4% inhibition of Staphylococcus aureus adhesion and 20.5% inhibition of biofilm formation. This castor oil-based polyurethane antimicrobial film is a promising alternative for coating the surfaces of equipment and devices used in the healthcare sector.
