拓扑学是对物体通过变形、扭曲和拉伸而保持的空间属性的数学研究。拓扑结构在自然界中是常见的,并且可以在例如在细胞事件期间凝聚和松弛的DNA分子中看到。合成的拓扑纳米结构,如索烃和轮烷,已经使用超分子化学工程,但复杂的和可重构的结构的制造仍然具有挑战性。在这里,我们表明,DNA折纸可以用来组装莫比乌斯带,一个拓扑带状结构,只有一边。此外,我们表明,DNA莫比乌斯带可以通过链置换重新配置,以创建拓扑对象,如超螺旋环和链烷结构。这种DNA折叠和切割策略类似于日本kirigami,可用于创建和重新配置分子工程中前所未有的可编程拓扑结构。
Topology is the mathematical study of the spatial properties that are preserved through the deformation, twisting and stretching of objects. Topological architectures are common in nature and can be seen, for example, in DNA molecules that condense and relax during cellular events. Synthetic topological nanostructures, such as catenanes and rotaxanes, have been engineered using supramolecular chemistry, but the fabrication of complex and reconfigurable structures remains challenging. Here, we show that DNA origami can be used to assemble a Möbius strip, a topological ribbon-like structure that has only one side. In addition, we show that the DNA Möbius strip can be reconfigured through strand displacement to create topological objects such as supercoiled ring and catenane structures. This DNA fold-and-cut strategy, analogous to Japanese kirigami, may be used to create and reconfigure programmable topological structures that are unprecedented in molecular engineering.
