Abstract
An improved method for enriched chirality of single wall carbon nanotubes is described. Genomic DNA, particularly salmon DNA (SaDNA) is shown to sort out single wall carbon nanotubes of specific chirality by a process of solubilization (dissolving in solution) and separation (such as centrifuging), without requiring more complex processes such as anion exchange chromatography. A possible reason for enhanced chirality separation using DNA may be attributed to its lowered GC (guanine-cytosine) content.
