Nanotubes can damage DNA, UD researchers find

Abstract:
University of Dayton researchers have found evidence of DNA damage and mutations in mice cells when exposed to carbon nanotubes — tiny synthetic structures being explored for a variety of medical uses, including delivering drugs and genes with unheard-of precision.

The study, published late last year by the American Chemical Society, is the first to demonstrate that carbon nanotubes can concentrate in stem cells and cause damage at the genetic level. Other studies, including those at UD, have found that some types of nanomaterials can be toxic at the cellular level.
