跳虫是生活在土壤、腐烂物质和植物上的节肢动物，它们通过进化出极其有效和坚固的防粘皮肤模式来适应苛刻的条件。然而，这些独特性质的细节及其结构基础仍然未知。在这里，我们表明，跳虫皮肤可以抵抗润湿的许多有机液体和高压。我们发现，刷毛和梳状六边形或菱形网格的相互连接的纳米级颗粒的组合区分皮肤的弹尾从抗粘附植物表面。此外，脊和颗粒轮廓中的负悬垂被揭示为跳虫皮肤的高度有效但尚未被忽视的设计原则。我们建议的非润湿特性的表面组成的这种配置文件，无论化学成分的解释。许多有价值的机会来自于将所描述的梳状图案和弹尾虫皮肤的悬垂轮廓转化为人造表面，该人造表面将抗磨损和摩擦的稳定性与上级的非润湿和抗粘附特性相结合。
Springtails, arthropods who live in soil, in decaying material, and on plants, have adapted to demanding conditions by evolving extremely effective and robust anti-adhesive skin patterns. However, details of these unique properties and their structural basis are still unknown. Here we demonstrate that collembolan skin can resist wetting by many organic liquids and at elevated pressures. We show that the combination of bristles and a comb-like hexagonal or rhombic mesh of interconnected nanoscopic granules distinguish the skin of springtails from anti-adhesive plant surfaces. Furthermore, the negative overhang in the profile of the ridges and granules were revealed to be a highly effective, but as yet neglected, design principle of collembolan skin. We suggest an explanation for the non-wetting characteristics of surfaces consisting of such profiles irrespective of the chemical composition. Many valuable opportunities arise from the translation of the described comb-like patterns and overhanging profiles of collembolan skin into man-made surfaces that combine stability against wear and friction with superior non-wetting and anti-adhesive characteristics.
