摘要
Over the past few decades, DNA has turned into one of the most widely used molecular linkers and a versatile building block for the self-assembly of DNA nanostructures. Such complexes, composed of only a few oligonucleotides (e.g., DNA tiles) or assembled from hundreds of synthetic and natural scaffolding strands (e.g., DNA origami), are being increasingly assembled into higher-order architectures such as lattices and crystals. A wide variety of assembly methods and techniques (e.g., solution-phase and substrate-assisted sticky-ended cohesion or blunt-end stacking) have emerged and are constantly being refined. This review provides a summary of the methods and building blocks for the assembly of 2D and 3D DNA lattices and crystals, and discusses some of their potential applications in materials science.
