Figure 3
From: Extrapulmonary transport of MWCNT following inhalation exposure
Enhanced darkfield images of MWCNT fibers in the diaphragm, kidney and brain at 1Â day and 336Â days after inhalation exposure. MWCNT fibers in these figures are bright white, cell nuclei are brownish red and other tissue elements are green. With rare exceptions, MWCNT fibers detected in extrapulmonary organs were singlets. Normal (transmitted) light was blended into the fields and contrast adjusted to make the tissue histology of the organs visible in these photographs.
