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.
本发明提供的聚合物基滑溜液体注入多孔表面(SLIPS)可以防止真菌和细菌病原体的粘附和定植,还可以杀死和/或减弱非粘附病原体在周围介质中的定植和毒力。本方法利用这些滑溜材料中的聚合物和液态油相来持续释放小分子,如广谱抗微生物剂、抗真菌剂、抗菌剂、调节细菌或真菌法定量感应的制剂、减弱毒性的制剂或其组合。这种可控释放方法改善了 SLIPS 固有的防污特性,具有通用性,并扩大了滑溜防污表面在基础和应用领域的潜在用途。
