(A) Quantification of fluorescence over time in different
regions of mice after intravenous injection of ssCTTC3TTC-SWCNT.
Results are averaged for 5 mice and error bars represent standard deviation.
Insets represent the average fluorescence intensity in the specified region
immediately following injection. Error bars have been removed for clarity
(B) Fluorescence image of the reporter in vivo
in a mouse, twenty-four hours after intravenous injection (200 ng).
(C) Fluorescence image of the reporter in mouse organs
ex vivo, twenty-four hours after injection as in (B).
(D) Quantification of ssCTTC3TTC-SWCNT emission
spectra ex vivo obtained with a near-infrared spectroscope.
****P < 0.0001 versus other groups, one way ANOVA
with Dunnet’s post test error bars represent standard deviation, N=3 mice
per group. (E) Quantification of ssCTTC3TTC-SWCNT
emission in isolated murine Kupffer cells (KCs), hepatocytes (HPs), and hepatic
stellate cells (HSCs), 24 hours after intravenous injection.
***P < 0.001, one way ANOVA with Tukey’s post
test, N=49–62 cells per group, error bars represent standard error of the
mean.
