Abstract

Carbon nanotubes¹ are cylindrical carbon molecules and can be considered to be composed of one atom thick sheets of carbon called graphene. They have been at the forefront of nanochemistry due to their strength and multiple properties such as absorption, fluorescence, semiconduction, and light scattering capability. DNA Origami (DO)² has emerged as a novel domain for molecular design, resulting in the generation of numerous one, two, and three-dimensional structures that have provided platforms for the organization of organic species and inorganic nanoparticles through simple modifications. The use of DNA Origami to control the placement of single walled carbon nanotubes (SWCNT) with precise alignment,³ purity and length would be a significant advance in controlled nanoscale organization.⁴ G-quadruplex (G4) secondary structures are guanine rich ssDNA sequences which fold to create square planar guanine tetrads.⁵ When G4 is introduced to Hemin, a (G4)/hemin-based DNA enzyme (DNAzyme) self assembles and possesses horseradish peroxidase (HRP)-mimicking catalytic properties.⁶ In this work, multiple approaches for the immobilization of SWCNTs at precisely designated locations on cross shaped DNA origami⁷ were implemented, and the results interpreted.
