Nano Safe

How toxic are nanomaterials? A group of scientists from US and Korea has shown that nanostructured composite microspheres can be easily prepared using ultrasound in a non-toxic manner. These microspheres were created to act as drug carriers, in particular to deliver a potent Alzheimer’s Disease drug which is in clinical trials. Before drug delivery, however, the scientists had to show that their carrier was not itself toxic to cells.

“With increasing concerns that synthetic nanomaterials may be highly toxic on all-levels of life and harmful to the environment, it would be good practice if researchers can report toxicology data along with their synthesis,” team member Yoo-Hun Suh of Seoul University told us.
