Fig. 6From: Single-walled carbon nanotubes modulate pulmonary immune responses and increase pandemic influenza a virus titers in miceNear infrared fluorescence (NIRF) imaging for tracking SWCNT in mice. C57BL/6 mice were exposed to SWCNT (20 μg per mouse) on day 0 and then to IAV (3.2×104 TCID50 per mouse) on day 3. On day 7 mouse lungs were stored in PFA and paraffin sections were prepared. H&E stained sections were probed with NIRF imaging and images aligned. a, c H&E SWCNT only images; b, d overlaid H&E and NIRF SWCNT only images; e, g H&E SWCNT + IAV images; f, h overlaid H&E and NIRF images for SWCNT + IAVBack to article page
