抗生物污染表面由于其在生物传感器、生物医学设备、食品加工、海洋工业等中的关键作用而非常重要。然而，传统的基于生物杀灭化合物释放或表面化学/物理设计的抗生物污染表面在满足真实的世界复杂条件时无法满足实际需求。天然抗生物污染表面的卓越性能推动了新型仿生抗生物污染表面的开发。在此，提出了一种基于超润湿性合理设计仿生抗生物污染表面的新策略。通过利用被困的气垫或液体层，荷叶启发的超疏水表面、鱼鳞启发的水下超疏油表面和猪笼草启发的全憎湿滑表面已成功地被设计为抗生物污染表面，以有效地抵抗蛋白质、细菌、细胞和海洋生物。相信这些新型的基于超润湿性的抗生物污损表面将为生物医学技术和海洋工业带来一个新时代，并将在不久的将来极大地造福于人类的健康和日常生活。
Anti‐biofouling surfaces are of high importance owing to their crucial roles in biosensors, biomedical devices, food processing, the marine industry, etc. However, traditional anti‐biofouling surfaces based on either the release of biocidal compounds or surface chemical/physical design cannot satisfy the practical demands when meeting real‐world complex conditions. The outstanding performances of natural anti‐biofouling surfaces motivate the development of new bioinspired anti‐biofouling surfaces. Herein, a novel strategy is proposed for rationally designing bioinspired anti‐biofouling surfaces based on superwettability. By utilizing the trapped air cushions or liquid layers, Lotus leaf inspired superhydrophobic surfaces, fish scales inspired underwater superoleophobic surfaces, andNepenthespitcher plants inspired omniphobic slippery surfaces have been successfully designed as anti‐biofouling surfaces to effectively resist proteins, bacteria, cells, and marine organisms. It is believed that these novel superwettability‐based anti‐biofouling surfaces will bring a new era to both biomedical technology and the marine industry, and will greatly benefit human health and daily life in the near future.
