Abstract
A method is described that involves creating bundles of semi-conducting CNTs by passing electromagnetic radiation through a solution containing individual DNA/metallic CNT hybrid structures and individual DNA/semi-conducting CNT hybrid structures. The method also involves segregating the bundles of semi-conducting CNTs from the DNA/metallic CNT hybrid structures. Another method is described for targeting for selection CNTs of specific diameter and chirality from a solution containing DNA/CNT hybrid structures.

A method, comprising:
- creating bundles of semi-conducting CNTs by exposing a solution containing individual DNA/metallic CNT hybrid structures and individual DNA/semi-conducting CNT hybrid structures to electromagnetic radiation;
- and,
- segregating said bundles of semi-conducting CNTs from said DNA/metallic CNT hybrid structures.
A method, comprising:
- creating a solution comprising:
- 1) individual DNA/metallic CNT hybrid structures;
- 2) individual DNA/semi-conducting CNT hybrid structures;
- 3) molecules made up of products that react with DNA so as to decompose said DNA
- creating bundles of semi-conducting CNTs by exposing said solution to electromagnetic radiation to cause at least a portion of said molecules to break up into their products because they received electrons from at least a portion of said DNA/semi-conducting CNT hybrid structures;
- and,
- segregating said bundles of semi-conducting CNTs from said DNA/metallic CNT hybrid structures.
