This article examines the DNA-based self-assembly of nanostructures. It first reviews the development of DNA self-assembly and DNA-directed assembly, focusing on the main strategies and building blocks available in the modern molecular construction toolbox, including the design, construction, and analysis of nanostructures composed entirely of synthetic DNA, as well as origami nanostructures formed from a mixture of synthetic and biological DNA. In particular, it considers the stepwise covalent synthesis of DNA nanomaterials, unmediated assembly of DNA nanomaterials, hierarchical assembly, nucleated assembly, and algorithmic assembly. It then discusses DNA-directed assembly of heteromaterials such as proteins and peptides, gold nanoparticles, and multicomponent nanostructures. It also describes the use of complementary DNA cohesion as 'smart glue' for bringing together covalently linked functional groups, biomolecules, and nanomaterials. Finally, it evaluates the potential future of DNA-based self-assembly for nanoscale manufacturing for applications in medicine, electronics, photonics, and materials science.

Optical tweezers have been used as versatile tools for non-contact manipulation of micrometer-sized entities. This paper proposes a hybrid micro/nanoscale manufacturing system using optical tweezers and chemical linkages for fabricating 2D and 3D micro/nanostructures. A holographic multiple trap optical tweezers system is first used to trap particles in a desired pattern. The particles are then connected to form rigid units using suitable chemistry. Connection schemes based on gold seeding, complementary-DNA linkage and streptavidin-biotin chemistry are presented and possible applications of this technique are explored. This method combines the advantages of top-down and bottom-up approaches and is compatible with organic and inorganic materials.

Microfabrication Techniques

Chemically synthesized nanostructures such as nanowires1, carbon nanotubes2 and quantum dots3 possess extraordinary physical, electronic and optical properties that are not found in bulk matter. These characteristics make them attractive candidates for building subsequent generations of novel and superior devices that will find application in areas such as electronics, photonics, energy and biotechnology. In order to realize the full potential of these nanoscale materials, manufacturing techniques that combine the advantages of top-down lithography with bottom-up programmed assembly need to be developed, so that nanostructures can be organized into higher-level devices and systems in a rational manner. However, it is essential that nanostructure assembly occur only at specified locations of the substrate and nowhere else, since otherwise undesirable structures and devices will result. Towards this end, we have developed a hybrid micro/nanoscale-manufacturing paradigm that can be used to program the assembly of nanostructured building blocks at specific, pre-defined locations of a chip in a highly parallel fashion. As a prototype system we have used synthetic DNA molecules and gold nanoparticles modified with complementary DNA strands as the building blocks to demonstrate the highly selective and specific assembly of these nanomaterials on lithographically patterned substrates.
