Abstract
Nucleic acids hold great promise for bottom-up construction of nanostructures via programmable self-assembly. Especially, the emerging of advanced sequence design principles and the maturation of chemical synthesis of nucleic acids together have led to the rapid development of structural DNA/RNA nanotechnology. Diverse nucleic acids-based nano objects and patterns have been constructed with near-atomic resolutions and with controllable sizes and geometries. The monodispersed distribution of objects, the up-to-submillimeter scalability of patterns, and the excellent feasibility of carrying other materials with spatial and temporal resolutions have made DNA/RNA assemblies extremely unique in molecular engineering. In this review, we summarize recent advances in nucleic acids-based (mainly DNA-based) near-atomic fabrication by focusing on state-of-the-art design techniques, toolkits for DNA/RNA nanoengineering, and related applications in a range of areas.
