In very high concentrations nanoclays cause cell damage. In vitro studies on cell cultures with regard to genetic modification (genotoxicity) are negative.

 

A valid study showed that cells are damaged when the particle concentration is very high. In the same study, it was also shown that no damage to the DNA was observed (no genotoxicity) and no reactive oxygen species occur (no ROS) [1].
