Sequence-encoded self-assembly of multiple-nanocomponent arrays by 2D DNA scaffolding.

چکیده
Regular 2D arrays of multiple types of nanocomponents were constructed by self-assembly to DNA scaffolding with alternating rows of sequence-encoded hybridization sites. Different-sized Au particles coated with DNA complementary to one of the sites were bound to the scaffolding, producing alternating rows of the two nanocomponents with a 32-nm inter-row spacing. These results demonstrate the potential for using DNA to self-assemble complex arrays of components with nanometer-scale precision.

DNA-Templated Self-Assembly of Metallic Nanocomponent Arrays on a Surface
A method for laying out arrays of components in programmable 2D arrangements with nanometer-scale precision is needed for the manufacture of high density nanoelectronic circuitry. We report programmed self-assembly of gold prototype nanoelectronic components into closely packed rows with precisely defined inter-row spacings by in situ hybridization of DNA-functionalized components to a preassem...
متن کاملCutting edge approaches to drug design
Going for gold To demonstrate the viability of this approach to manufacturing electrical circuitry, Kiehl’s team is investigating an assembly of gold nanoparticles into linear arrays on the DNA scaffolding. In their approach, a set of short DNA strands with different sequences are formed into DNA tiles that self-assemble into a DNA crystal.The particles are assembled onto the DNA scaffolding by...
متن کاملSelfassembly of metallic nanoparticle arrays by DNA scaffolding
We report the self-assembly of metallic nanoparticle arrays using DNA crystals as a programmable molecular scaffolding. Gold nanoparticles, 1.4 nm in diameter, are assembled in two-dimensional arrays with interparticle spacings of 4 and 64 nm. The nanoparticles form precisely integrated components, which are covalently bonded to the DNA scaffolding. These results show that heterologous chemical...
متن کاملSelf-assembled DNA Structures for Nanoconstruction
In recent years, a number of research groups have begun developing nanofabrication methods based on DNA self-assembly. Here we review our recent experimental progress to utilize novel DNA nanostructures for self-assembly as well as for templates in the fabrication of functional nano-patterned materials. We have prototyped a new DNA nanostructure known as a cross structure. This nanostructure ha...
متن کاملProgrammed two-dimensional self-assembly of multiple DNA origami jigsaw pieces.
We demonstrate a novel strategy of self-assembly to scale up origami structures in two-dimensional (2D) space using multiple origami structures, named "2D DNA jigsaw pieces", with a specially designed shape. For execution of 2D self-assembly along the helical axis (horizontal direction), sequence-programmed tenon and mortise were introduced to promote selective connections via π-stacking intera...
