New research from NIST: Catching and releasing nanoparticles helps determine if they are safe

Nanoparticle safety has become a major worry in recent years.  In 2007, there was evidence discovered that some nanoparticles could damage DNA and lead to cancer.  This led to a call for studies on the safety of different types of nanoparticles. 

Yesterday, an article we found online at Science Daily's website (here's a link: discussed some work along these lines by researchers at NIST.  They figured out a way to capture nanoparticles, where they could be exposed to cells to see whether they are pose a hazard, then released.
