Rings of single-walled carbon nanotubes
The assembly and manipulation of nanoscale building blocks are among the most important scientific challenges in nanoscience because they not only afford a potential route to the fabrication of large-scale integrated nanoscale devices but also provide a better understanding of the issues that govern self-organization in many classes of materials.
A group of researchers at the Institute for Nanotechnology at Northwestern University have recently developed a directed assembly approach for positioning and shaping single-wall carbon nanotubes (SWNTs) into rationally designed structures based upon their interaction with nanopatterned monolayer templates.
