Gecko feet integrate many intriguing functions such as strong adhesion, easy detachment, and self-cleaning. Mimicking gecko toe pad structure leads to the development of new types of fibrillar adhesives useful for various applications. In this Concept article, in addition to the design of adhesive mimics by replicating gecko geometric features, we show a new trend of rational design by adding other physical, chemical, and biological principles on to the geometric merits, for enhancing robustness, responsive control, and durability. Current challenges and future directions are highlighted in the design and nanofabrication of biomimetic fibrillar adhesives.
壁虎的脚整合了许多有趣的功能，如强力附着、易于脱离和自清洁。模仿壁虎脚趾垫的结构导致了新型纤维状粘合剂的发展，这些粘合剂可用于各种应用。在这篇概念文章中，除了通过复制壁虎的几何特征来设计粘性模仿物之外，我们还展示了一种通过在几何优点上添加其他物理、化学和生物学原理来增强稳健性、响应控制和耐久性的合理设计的新趋势。在仿生纤维状粘合剂的设计和纳米制造中，突出了当前的挑战和未来的方向。
