title: Protective roles of single-wall carbon nanotubes in ultrasonication-induced DNA base damage.
abstract: The overall level of ultrasonication-induced DNA damage is reduced in the presence of single-wall carbon nanotubes (SWCNTs), particularly for DNA lesions formed by one-electron reduction of intermediate radicals. The protective role of SWCNTs observed in this work suggests a contrary view to the general idea that carbon nanotubes have damaging effects on biomolecules.
