Behavioral properties of biotinylated SWNT compared to those of the non-biotinylated SWNT. (a) Fluorescence emission spectra for 30 mg/L biotinylated SWNT and non-biotinylated SWNT. (b,c) Isolated 990 intensity values for biotinylated SWNT and non-biotinylated SWNT are not significantly different (as designated by n.s.). (d) Normalized fluorescence spectra demonstrate nearly identical fwhm values. (e) Fluorescence quenching curves in response to identical concentrations of NO demonstrate that biotinylation has a negligible effect on SWNT quenching response. (n = 3 for a–e, unpaired t-test demonstrated a lack of statistical differences between samples).
