Abstract
The application of single-walled carbon nanotubes encapsulated by a DNA oligonucleotides (DNA-SWNT) as photo-bleaching resistant, non-quenching markers which remained functional in live cells were investigated. Raman scattering and fluorescence spectra of DNA-SWNT were measured from within live as well as hematoxylin and eosin stained cells, showing continued emission after staining and spectral changes upon uptake. Nanotubes were suspended with a 30-base alternating GT sequence of single-stranded DNA. Nanotubes were found to incorporate into cytoplasmic vesicles and labeled the prenuclear region of the cells, but did not enter the nuclear envelope.
