摘要：
We demonstrate a versatile process for assembling micron-scale filament architectures by controlling where DNA tile nanotubes nucleate on DNA origami assemblies. "Nunchucks," potential mechanical magnifiers of nanoscale dynamics consisting of two nanotubes connected by a dsDNA linker, form at yields sufficient for application and consistent with models.
