Nanoparticles may cause DNA damage across a cellular barrier

Description

Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The nanoparticles did not cause the damage by passing through the barrier, but generated signalling molecules within the barrier cells that were then transmitted to cause damage in cells the other side of the barrier.
The research was carried out by a team at the University of Bristol and colleagues, and is published online this week in Nature Nanotechnology.
