Light May Skew Lab Tests on Nanoparticles' Health Effects

November 19, 2014 2:00 pm | by NIST | News | Comments

Truth shines a light into dark places. But sometimes to find that truth in the first place, it’s better to stay in the dark. That’s what recent findings show about methods for testing the safety of nanoparticles. It turns out that previous tests indicating that some nanoparticles can damage our DNA may have been skewed by inadvertent light exposure in the lab.
