Bottom-up Nanofabrication Using DNA Nanostructures

Abstract

DNA nanostructures are ideal templates for bottom-up assembly and fabrication of nanomaterials. Their structures can be tailored for a given application and modified with pinpoint precision. They offer the best of top down and bottom up assembly. We highlight recent progress in DNA nanotechnology and in particular advances that are relevant to the materials chemistry community. Examples of using DNA nanostructure to address materials chemistry challenges are highlighted.

Adsorption characteristics of Cytochrome c/DNA complex Langmuir molecular assemblies at the air–water interface: a surface area-normalized isotherm study

“…In recent times, DNA based nanoarchitechtures have attracted widespread interest because of their signicant role in developing nanoscaled scaffolds, frameworks and wires. [3][4][5][6] On the other hand, electron transfer between proteins plays a vital role both in photosynthesis which harvests light energy as well as in metabolism that oxidizes fuel. This long range energy transfer may be attributed to the wellcontrolled interfacial associations of proteins.…”

Seeding, Plating and Electrical Characterization of Gold Nanowires Formed on Self-Assembled DNA Nanotubes

“…Nanofabrication, which is used to construct structures and devices with minimum dimensions below 100 nm [ 1 ], is having a significant impact on diverse areas, such as electronics, biomedicine, materials and so forth [ 2 ]. Most current nanofabrication relies on top-down technology [ 3 ], which is highly automated but also expensive and requires complicated instrumentation [ 4 ].…”

“…Thus, nanofabrication could benefit from alternative techniques, including bottom-up approaches wherein chemical or physical forces operating at the nanoscale assemble smaller parts into larger structures [ 5 ]. Bottom-up methods produce less waste, utilize less expensive tools and offer straightforward scaling up compared to top-down nanofabrication [ 1 , 3 ]. Examples of bottom-up techniques include molecular self-assembly and atomic layer deposition [ 6 ].…”
