Abstract
Unlike most adhesive bonds, biological catch bonds strengthen with increased tension. This characteristic is essential to specific receptor-ligand interactions, underpinning biological adhesion dynamics, cell communication, and mechanosensing. While artificial catch bonds have been conceived, the tunability of their catch behaviour is limited. Here, we present the fish-hook, a rationally designed DNA catch bond that can be finely adjusted to a wide range of catch behaviours. We develop models to design these DNA structures and experimentally validate different catch behaviours by single-molecule force spectroscopy. The fish-hook architecture supports a vast sequence-dependent behaviour space, making it a valuable tool for reprogramming biological interactions and engineering force-strengthening materials.
与大多数粘合剂不同，生物捕捉键会随着张力的增加而增强。这一特性对于特定的受体-配体相互作用至关重要，是生物粘附动力学、细胞通讯和机械传感的基础。虽然已经构想出了人工捕捉键，但其捕捉行为的可调性却很有限。在这里，我们展示了鱼钩，这是一种经过合理设计的 DNA 捕获键，可以根据各种捕获行为进行微调。我们开发了设计这些 DNA 结构的模型，并通过单分子力谱仪对不同的捕捉行为进行了实验验证。鱼钩结构支持广阔的序列依赖行为空间，使其成为重新编程生物相互作用和工程力强化材料的重要工具。
