The abundance of pathogenic microorganisms in the environment and the ease of their transmission through several paths is a critical issue in many daily human activities. Within the different transmission paths, contact with contaminated surfaces provides a chance for the development of surfaces with special characteristics that are able to reduce the spread of microorganisms through their deactivation by contact. The development of 'active' surfaces with antiviral properties requires the understanding of the molecular interaction mechanisms between functionalised surfaces and lipid-enveloped entities. By means of a study based on experimental and computational methods we have assessed that surfaces that are simultaneously hydrophobic and oleophilic are more efficient for disinfecting aqueous virus solutions. The combination of these features causes the disruption of the viral lipid envelope upon contacting the surface, and as a consequence the virus' destruction and deactivation. Our results suggest new and more effective design strategies for functionalised surfaces that may be of interest for applications in sensitive environments.
