Template-Synthesized DNA Nanotubes

摘要

There is considerable interest in DNA-functionalized nanotubes with proposed applications that include use as gene delivery vehicles,in DNA-assisted separation and assembly of carbon nanotubes,and in nanotube-based DNA sensing and separations.In all of these previous cases,the DNA was attached to a nanotube composed of a second material;it might also be advantageous to have nanotubes composed entirely,or predominately,of DNA itself.We describe here a template synthesis method for preparing such DNA nanotubes.
