It is notoriously difficult to observe, let alone control, the position and orientation of molecules due to their small size and the constant thermal fluctuations that they experience in solution. Molecular self-assembly with DNA enables building custom-shaped nanometer-scale objects with molecular weights up to the megadalton regime. It provides a viable route for placing molecules and constra...

Abstract Spatial organization on the atomic scale is one of key objectives nanotechnology. The development DNA nanotechnology a hallmark material programmability in 2D and 3D, which large variety available modifications allows it to be interfaced with number inorganic organic materials. Nature’s solution spatiotemporal control has been evolution self-organizing protein systems capable pattern f...

DNA and protein have been extensively scrutinized for feasibility as parts in nanotechnology, but another natural building block, RNA, has been largely ignored. RNA can be manipulated to form versatile shapes, thus providing an element of adaptability to DNA nanotechnology, which is predominantly based upon a double-helical structure. The DNA-packaging motor of bacterial virus phi29 contains si...

The specificity and predictability of Watson-Crick base pairing make DNA a powerful and versatile material for engineering at the nanoscale. This has enabled the construction of a diverse and rapidly growing set of DNA nanostructures and nanodevices through the programmed hybridization of complementary strands. Although it had initially focused on the self-assembly of static structures, DNA nan...

Synthetic DNA structures for nanotechnological applications have experienced substantial success during the past decades benefiting from Seeman and his coworkers' pioneering work. In the last few years, some new branches have been emerging in this field. This review will summarize some recent progress in the authors' group. Forming crystalline DNA lattices in one, two and even three dimensions ...

DNA-grafted nanoparticles have been called "programmable atom-equivalents": Like atoms, they form three-dimensional crystals, but unlike atoms, the particles themselves carry information (the sequences of the grafted strands) that can be used to "program" the equilibrium crystal structures. We show that the programmability of these colloids can be generalized to the full temperature-dependent p...

Rapid and accurate detection of genetic mutations based on nanotechnology would provide substantial advances in detection of polycystic kidney disease (PKD), a disease whose current methods of detection are cumbersome due to the large size and duplication of the mutated gene. In this study, a nanotechnology-based DNA assay was developed for detection of SNPs (single nucleotide polymorphisms) in...

A flexible strategy for the preparation of nanostructures of gold nanoparticles (AuNPs) through DNA directed assembly has been proposed. This strategy would greatly enhance the stability, precision and flexibility in the construction of DNA-base structural and functional devices, and promote the development of DNA nanotechnology.
