1. A method for growing single-wall carbon nanotubes comprising:

  • a) providing seed molecules comprising segments of single-wall carbon nanotubes;

    b) contacting the ends of the single-wall carbon nanotubes of the segments with at least one catalytic metal;

    c) activating the catalytic metal;

    d) adding a gaseous source of carbon to the single-wall carbon nanotubes and the catalytic metal;

    e) subjecting the single-wall carbon nanotubes, the catalytic metal and the gaseous source of carbon to conditions to grow to the single-wall carbon nanotubes;

    f) growing the segments of the single-wall carbon nanotubes; and

    g) recovering the grown single-wall carbon nanotubes.
