Physical and chemical modification of MWCNT in vivo: Physical modifications of MWCNT were observed by TEM on (A) control 2 and (B) MWCNT after intratracheal instillation. (C) Length quantification of MWCNT length was performed at least on 100 MWCNT per condition (Control1, control 2 and MWCNT after intratracheal instillation. Results are the mean of ± SD obtained on 3 independent experiment. * Significantly different (p < 0.05) from control group. (D) Chemical modifications of the MWCNT were assessed by infrared spectroscopy of (a) control 1, (b) control 2 and (c) MWCNT after intratracheal instillation. Spectra of a representative experiment performed on 3 rats.
