Abstract: The present invention provides polymer-based slippery liquid-infused porous surfaces (SLIPS) that can prevent adhesion and colonization by fungal and bacterial pathogens and also kill and/or attenuate the colonization and virulence of non-adherent pathogens in surrounding media. The present approach exploits the polymer and liquid oil phases in these slippery materials to sustain the release of small molecules such as a broad-spectrum antimicrobial agent, an antifungal agent, an antibacterial agent, an agent that modulates bacterial or fungal quorum sensing, an agent that attenuates virulence, or a combination thereof. This controlled release approach improves the inherent anti-fouling properties of SLIPS, has the potential to be general in scope, and expands the potential utility of slippery, non-fouling surfaces in both fundamental and applied contexts.
