PNNL researchers recently discovered that the smallest nano-sized silica particles used in biomedicine and engineering likely won’t cause unexpected biological responses due to their size.

Researchers at the Pacific Northwest National Laboratory (PNNL) recently discovered that the smallest nano-sized silica particles used in biomedicine and engineering likely won’t cause unexpected biological responses due to their size.

“The big fear is that you’d see unique biological pathways being affected when you get down to the nanoscale,” said nanotoxicologist Brian Thrall. “For the most part, we didn’t see that.”

Find out what the researchers did see by following the link below.
