Nanostructured
Possessing a structure comprising contiguous elements with one or more dimension in the nanoscale but excluding any primary atomic or molecular structure. NOTE 1 An example of a primary atomic or molecular structure is the arrangement of atoms in a crystalline solid. NOTE 2 The use of the term contiguous implies that a sphere, of approximately 100 nm diameter, inscribed in a nanostructured material will intersect more than one element of the structure.

Terminology for Nanotechnology Nanostructured, adj-containing physically or chemically distinguishable components, at least one of which is nanoscale in one or more dimensions.DISCUSSION-While many conventional nanomaterials are distinguished by physical or chemical characteristics, biological recognition may also be the basis for defining a nanostructure. Though this concept is formally contained by the word ‘chemically' such a feature would lead to a distinctive type of nanostructured system. Source: BSI. PAS 133:2007.
