Abstract

Unbound double-stranded DNA (dsDNA) was removed from an aqueous solution (solution 1) of dsDNA-solubilized single-walled carbon nanotubes (SWNTs) using size-exclusion chromatography (SEC). The SEC chromatogram of solution 1 showed two separated peaks, and the earlier eluent fraction was separated into four size-separated fractions, fr1-fr4, in which individually solubilized SWNTs were found to exist. The stability of the DNA/SWNT hybrids was evaluated by the re-injection of fr1-fr4. It was found that the chromatograms of fr1-fr4 were identical to those of the original ones even after storage for one month, indicating the high stability of the dsDNA/SWNT hybrids in water.
