Surface topography plays a key role in the colonization of substrata by the colonizing stages of marine fouling organisms. For the innovation of marine antifouling coatings, it is essential to understand how topographic cues affect the settlement of these organisms. In this study, tapered, spiked microstructures and discrete honeycombs of varying feature dimensions were designed and fabricated in order to examine the influence of topography on the attachment of zoospores of the green macroalga Ulva linza and cells of the diatom (microalga) Navicula incerta. Contrasting results were obtained with these two species of algae. Indeed, the preferred location of cells of N. incerta was dominated by attachment point theory, which suggested a positive correlation between the density of cells adhering and the amount of available attachment points, while the settlement of spores of U. linza was mainly regulated by both Wenzel roughness and local binding geometry.
表面形貌在海洋污损生物定殖阶段对基质的定殖过程中起着关键作用。对于海洋防污涂料的创新而言，了解形貌线索如何影响这些生物的附着至关重要。在本研究中，设计并制造了具有不同特征尺寸的锥形、尖峰微结构和离散蜂窝结构，以研究形貌对绿色大型海藻石莼游动孢子和硅藻（微藻）不确定舟形藻细胞附着的影响。这两种藻类获得了截然不同的结果。事实上，不确定舟形藻细胞的优先附着位置主要由附着点理论主导，该理论表明附着细胞的密度与可用附着点的数量之间存在正相关，而石莼孢子的附着主要受文泽尔粗糙度和局部结合几何形状的共同调节。
