Abstract:

The purpose of this study is to evaluate the length effects on cytotoxicity of multi-walled carbon nanotubes (MWCNTs) based on the murine derived multipotent neural stem cells (NSCs) line. Cellular viability of NSCs exposed to MWCNTs showed that the length of MWCNTs had impacts on their cytotoxicity. Meanwhile, cellular morphology and membrane integrality showed low toxicity of MWCNTs on NSCs. The result will benefit applications of CNTs.

Key words: multi-walled carbon nanotubes (MWCNTs); cytotoxicity; neural stem cells (NSCs)
