Illustration of t-ox-MWCNTs in rat subcutaneous tissue at 2 years after implantation.
(a) Illustration of t-ox-MWCNTs in the secondary lysosome within a macrophage. The outer layers of t-ox-MWCNTs in the lysosomes of macrophages are partially biodegraded. (b) Illustration of t-ox-MWCNTs located outside the macrophage. The large t-ox-MWCNT agglomerates present in the intercellular space are not biodegraded.
