Nanoparticles can damage the DNA of cells some distance away, even when the cells seem safe behind an impassable barrier of tissue, new research has found.
But what does this curious finding, revealed yesterday by researchers at the University of Bristol, UK, mean about the safety of nanoparticles and medical treatments based on them? New Scientist puts the news in context.
Did the experiment represent something that could happen in my body?
The experimental set-up was entirely artificial, and nothing like it occurs naturally in humans or animals. Nor are the nanoparticles in question used in any current treatments, experimental or otherwise.
