Invention of DNA origami has transformed the fabrication and application of biological nanomaterials. In this review, we discuss DNA origami nanoassemblies according to their four fundamental mechanical properties in response to external forces: elasticity, pliability, plasticity and stability. While elasticity and pliability refer to reversible changes in structures and associated properties, plasticity shows irreversible variation in topologies. The irreversible property is also inherent in the disintegration of DNA nanoassemblies, which is manifested by its mechanical stability. Disparate DNA origami devices in the past decade have exploited the mechanical regimes of pliability, elasticity, and plasticity, among which plasticity has shown its dominating potential in biomechanical and physiochemical applications. On the other hand, the mechanical stability of the DNA origami has been used to understand the mechanics of the assembly and disassembly of DNA nano-devices. At the end of this review, we discuss the challenges and future development of DNA origami nanoassemblies, again, from these fundamental mechanical perspectives.

DNA折纸纳米力学
DNA折纸技术的发明改变了生物纳米材料的制造和应用。在这篇综述中，我们根据 DNA 折纸纳米组件响应外力的四种基本机械特性进行讨论：弹性、柔韧性、可塑性和稳定性。弹性和柔韧性是指结构和相关属性的可逆变化，而塑性则显示拓扑结构的不可逆变化。不可逆特性也是 DNA 纳米组装体崩解所固有的，这通过其机械稳定性得到体现。过去十年中，不同的 DNA 折纸装置利用了柔韧性、弹性和可塑性的机械机制，其中可塑性在生物力学和物理化学应用中显示出其主导潜力。另一方面，DNA折纸的机械稳定性已被用来了解DNA纳米器件组装和拆卸的力学。在这篇综述的最后，我们再次从这些基本的机械角度讨论了 DNA 折纸纳米组件的挑战和未来发展。
