Chiral DNA origami nanotubes with well‐defined and addressable inside and outside surfaces

Angewandte Chemie International Edition Wiley‐VCH Verlag 57:26 (2018) 7687-7690

Authors:

F Benn, Natalie EC Haley, Alexandra E Lucas, Emma Silvester, Seham Helmi, R Schreiber, Jonathan Bath, Andrew J Turberfield

Abstract:

We report the design and assembly of chiral DNA nanotubes with well‐defined and addressable inside and outside surfaces. We demonstrate that the outside surface can be functionalised with a chiral arrangement of gold nanoparticles to create a plasmonic device and that the inside surface can be functionalised with a track for a molecular motor allowing transport of a cargo within the central cavity.
