(A) Ex vivo fluorescence imaging of the aortas from ApoE^−/− mice harvested 3 h post intravenous administration of TMV nanoparticles. The asterisks indicate the aortas used for Sudan IV staining in (C). (B) Quantitative analysis of ex vivo fluorescence images of (A); the total radiant efficiency was normalized to the area of interest. The radiant efficiency units are (p s⁻¹ cm⁻² sr⁻¹)/(μW cm⁻²). (C) Image of aortas after Sudan IV staining. The vertical scale bar is 1 cm.
