Single‑walled carbon nanotubes, or SWCNTs, are nanomaterials that possess unique characteristics, most importantly their differing structural arrangement in terms of chirality. Each single‑walled carbon nanotube exhibits a unique fluorescence spectra that is dependent upon its chirality. The association of single‑stranded DNA (ssDNA) with SWCNTs is monitored by near‑infrared fluorescence spectroscopy. The DNA:SWCNT hybrid exhibits fluorescence spectra dependence upon both the selected sequence and the selected chirality.
