Nanostructure

In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.

Nanotubes have two dimensions on the nanoscale, i.e., the diameter of the tube is between 0.1 and 100 nm; its length can be far more.

The terms nanoparticles and ultrafine particles (UFP) are often used synonymously although UFP can reach into the micrometre range.

The term nanostructure is often used when referring to magnetic technology.

Nanoscale structure in biology is often called ultrastructure.
