Abstract:

Nanotechnology and nanoparticle manufacture is expanding its area of influence. A variety of shapes and surface chemistries of nanoparticles exists at this time; however, little can be predicted regarding the contribution of these characteristics to human health. To address this knowledge gap we have compiled a suite of assays to determine if biomedically-relevant, well characterized nano-materials cause damage to genomic DNA and if the observed DNA damage is correlated/associated with cytotoxic stress in well-characterized cell systems.
