Study Notes
Defining Nanomaterials
- Nanomaterials are defined as materials with structure at the nanoscale, typically in the size range of 1-100 nanometers (nm).
Nanomaterial Definition
- According to ISO/TS 80004, a nanomaterial is a material with one or more external dimensions, or an internal structure, on the nanoscale.
Properties of Nanomaterials
- Materials with structure at the nanoscale often have unique physical, chemical, and biological properties that differ from their bulk counterparts.
Nano-Objects
- According to ISO/TS 80004, nano-objects are materials with one, two, or three external dimensions in the nanoscale (typically in the range of 1-100 nm).
Nanoscale
- The length range of the nanoscale, according to ISO/TS 80004, is approximately 1-100 nm.
