Abstract
Single-walled carbon nanotubes (SWNTs) are dispersed in water via wrapping with short segments of single-stranded DNA (ssDNA). Small-angle neutron scattering suggests that the aqueous SWNT suspensions are only marginally stable, and we exploit this to make hydrophillic colloidal particles coated and stabilized by the SWNT-ssDNA complex. Near-infrared fluorescence microscopydemonstrates the band-gap fluorescence of these SWNT-coated particles, suggesting potential routes to novel platforms and applications.
