By designing self-assembling parts, researchers have discovered how to make nanotubes with specific sizes and traits.
Hicham Fenniri and his team at Purdue University in West Lafayette, Ind., constructed unique molecules as building blocks for nanotubes. Each 1-nanometer molecule contains carbon, nitrogen, oxygen, and hydrogen atoms arranged to resemble the DNA base guanine on one edge of the molecule and cytosine on the other. In DNA, these two bases naturally couple.
