摘要

MWCNT and SiO_2 NP are widely used as nanofillers in polymeric matrices for different applications. We have studied the cytotoxicity of these NM at the different stages of the life cycle in A549 and HepG2 cell lines. To evaluate NM (MWCNT and SiO_2 NP) at the different stages of the life cycle, these NM were recovered from the polymer matrix by different processes, either by calcination of the polymer nanocomposite or by dissolution followed by filtration or centrifugation. These processes induced surface modification on the NM that were reflected in their toxicological profile. In the case of MWCNT calcination processes leaded to higher cytotoxicity and for hydrophilic SiO_2 NP after the have been recovered by calcination they are not cytotoxic anymore. Surface chemistry is driving the cytotoxic effects of NM along their life cycle.
