Abstract	Water-soluble DNA-wrapped single-wall and double-wall carbon nanotubes (DNA-SWNTs, DNA-DWNTs) have been well separated by length incorporating size-exclusion high-performance liquid chromatography (HPLC). The morphology and electronic properties of the size- (length-) separated DNA-SWNTs and -DWNTs are investigated by atomic force microscopy (AFM), photoluminescence (PL), and Raman spectroscopy. By using length-separated DNA-SWNTs and -DWNTs, we have found that PL intensity of the DNA-SWNTs varies sensitively depending not only on the chirality (or diameter) but more importantly on the length of the hybrids.
