Nanosized materials
Nanomaterials, natural and human made, are characterized by size, measured in nanometers. A nanometer is one millionth of a millimeter - about 100,000 times smaller than the diameter of a single hair. NIEHS is working to understand any potential risks associated with exposure to these materials.
