Description
Deoxyribonucleic acid (DNA) has emerged as an excellent molecular building block for nanoconstruction in addition to its biological role of preserving genetic information. Its unique features such as predictable conformation and programmable intra- and inter-molecular Watson-Crick base pairing interactions make it a remarkable engineering material. A variety of convenient design rules and reliable assembly methods have been developed to engineer DNA nanostructures. The ability to create designer DNA architectures with accurate spatial control has allowed researchers to explore novel applications in directed material assembly, structural biology, biocatalysis, DNA
computing, nano-robotics, disease diagnosis, and drug delivery.
This dissertation focuses on developing the structural design rules for "static" DNA nano-architectures with increasing complexity. By using a modular self-assembly method, Archimedean tilings were achieved by association of different DNA motifs with designed arm lengths and inter-tile sticky end interactions. By employing DNA origami method, a new set of design rules was created to allow the scaffolds to travel in arbitrary directions in a designed geometry without local symmetry restrictions. Sophisticated wireframe structures of higher-order complexity were designed and constructed successfully. This dissertation also presents the use of "dynamic" DNA nanotechnology to construct DNA origami nanostructures with programmed reconfigurations.
