From The Guardian:

Lab tests show that metal nanoparticles can affect DNA without actually coming into contact with it – though the results are difficult to extrapolate to the human body.

Nanoparticles of metal can damage the DNA inside cells even if there is no direct contact between them, scientists have found. The discovery provides an insight into how the particles might exert their influence inside the body and points to possible new ways to deliver medical treatments.
