DNA是最受欢迎的生物聚合物,用于表现出纳米尺度特征的物体和设备的程序化自组装。DNA纳米结构的最有用的特性之一是它们能够被额外的非核酸组分官能化。这种组分的引入通常通过将其连接到作为纳米结构的一部分的寡核苷酸上,或将其杂交到延伸超过纳米结构表面或在纳米结构表面上方的单链突出端上来实现。然而,纳米结构设计和/或自组装过程中的限制可能会限制这些程序的适用性。另一种策略是将组分偶联到能够结合纳米结构内的双链体序列的DNA识别剂。这提供了这样的优点,即它需要对纳米结构进行很少(如果有的话)的改变,并且可以在结构组装之后实现。此外,由于DNA的分子识别可以通过改变pH和离子条件来控制,因此这种系统提供了不同于简单沃森-克里克杂交的可调性质。在这里,我们描述的方法,已被用来开发和表征DNA纳米结构的序列特异性识别,与生物纳米技术和合成生物学应用的目的是产生功能组件。
DNA is the most exploited biopolymer for the programmed self-assembly of objects and devices that exhibit nanoscale-sized features. One of the most useful properties of DNA nanostructures is their ability to be functionalized with additional non-nucleic acid components. The introduction of such a component is often achieved by attaching it to an oligonucleotide that is part of the nanostructure, or hybridizing it to single-stranded overhangs that extend beyond or above the nanostructure surface. However, restrictions in nanostructure design and/or the self-assembly process can limit the suitability of these procedures. An alternative strategy is to couple the component to a DNA recognition agent that is capable of binding to duplex sequences within the nanostructure. This offers the advantage that it requires little, if any, alteration to the nanostructure and can be achieved after structure assembly. In addition, since the molecular recognition of DNA can be controlled by varying pH and ionic conditions, such systems offer tunable properties that are distinct from simple Watson–Crick hybridization. Here, we describe methodology that has been used to exploit and characterize the sequence-specific recognition of DNA nanostructures, with the aim of generating functional assemblies for bionanotechnology and synthetic biology applications.
