Biological Effects of the Carbon Nanotubes

The influences of the carbon nanotubes on proliferation state of chick embryo fibroblast cells and toxicity of the nanotubes to the cells have been investigated by 3-(4,5-dimethylthiazol 2-yl)-2,5 diphenylte-trazolium bromide (MTT) colorimetric method of Mosmann and the toxicology. We found that the toxicity of the carbon nanotubes to the chick embryo fibroblast cells is small, it is about first score (or degree)
