Figure 6.
(A) Impact of human blood plasma on the fluorescence emission spectra of CB13-DNA-SWNT and the resulting change upon addition of 100 μM DOX. (B) Brightfield image of mouse muscle excised from the upper hind leg. (C) NIR image of muscle tissue from the same field of view as B, revealing fluorescence from CB13-DNA-SWNT localized in the muscle tissue. Scale bar is 100 μm. (D) Emission spectra collected from (B) before (black) and after (red) addition of 100 μM DOX to the sample bath. (E) Intensity ratio of long-wavelength fluorescence to short-wavelength fluorescence for CB13-DNA-SWNT in mouse tissue before and after addition of 100 μM DOX.
