Assembly of Carbon Nanotubes on Linear Origami

Carbon nanotubes have been celebrated in recent years for their incredible physical properties, but there exists a significant lack of organizational capability with regards to their employment. In this proposal, a uniquely modified linear array of DNA origami is presented as a substrate for the organized assembly of carbon nanotubes. This method relies on the presence of DNA docking strand sequences that are specific6 to carbon nanotubes of 6, 5 chirality to centrally align the carbon nanotubes along the linear DNA origami array. When exposed to thermal annealing, the docking strands should bind the carbon nanotubes, producing a one-dimensional array of DNA origami with carbon nanotubes aligned along its length. The merit of this approach stems from its relative simplicity, ease of execution, and inexpensiveness compared to currently existing methods for carbon nanotube alignment8, 9. However, this method may present challenges in terms of nonspecific alignment, although these should be addressable with refinements to the origami design and/ or the annealing conditions. If successful, this project would define a convenient method for the linear alignment of carbon nanotubes that does not require esoteric or expensive techniques or reagents to execute. In addition, the success of this project would define the groundwork for the extension of linear array concepts to dually functionalized linear arrays (e.g. carbon nanotubes and proteins) and two-dimensional DNA origami arrays that could be similarly functionalized. It is expected that the goal of this project should be realistic to accomplish within the allotted 11 weeks of the SURE program. This is especially true due to the lack of need to learn new techniques or purchase new equipment to execute the process outlined in this proposal.
