Figure 2. Parenchymal distribution of MWNT-NH₃ ⁺and oxMWNT-NH₃ ⁺ after stereotactic administration in the motor cortex of C57BL/6 mice by light microscopy of H&E stained coronal sections, two weeks after injection with nanotubes.

A) MWNT-NH₃ ⁺; B) oxMWNT-NH₃ ⁺; C) High magnification images of the MWNT-NH₃ ⁺ injected tissue. Cortex (CX), ependymal layer (EL), and ventricles (VT) are noted, respectively. The distance from the Bregma line for each section is indicated above each image. Black arrows indicate the presence of f-MWNTs in the sections.
