2.1

nanoscale

length range approximately from 1 nm to 100 nm

Note 1 to entry: Properties that are not extrapolations from larger sizes are predominantly exhibited in this length range.

2.2

nanoscience

study, discovery and understanding of matter where size- and structure-dependent properties and phenomena manifest, predominantly in the nanoscale (2.1) , distinct from those associated with individual atoms or molecules, or extrapolation from larger sizes of the same material

2.3

nanotechnology

application of scientific knowledge to manipulate and control matter predominantly in the nanoscale (2.1) to make use of size- and structure-dependent properties and phenomena distinct from those associated with individual atoms or molecules, or extrapolation from larger sizes of the same material

Note 1 to entry: Manipulation and control includes material synthesis.

2.4

nanomaterial

material with any external dimension in the nanoscale (2.1) or having internal structure or surface structure in the nanoscale

Note 1 to entry: This generic term is inclusive of nano-object (2.5) and nanostructured material (2.7) .

Note 2 to entry: See also definitions 2.8 to 2.10.

2.5

nano-object

discrete piece of material with one, two or three external dimensions in the nanoscale (2.1)

Note 1 to entry: The second and third external dimensions are orthogonal to the first dimension and to each other.

2.6

nanostructure

composition of inter-related constituent parts in which one or more of those parts is a nanoscale (2.1) region

Note 1 to entry: A region is defined by a boundary representing a discontinuity in properties.

2.7

nanostructured material

material having internal nanostructure (2.6) or surface nanostructure

Note 1 to entry: This definition does not exclude the possibility for a nano-object (2.5) to have internal structure or surface structure. If external dimension(s) are in the nanoscale (2.1) , the term nano-object is recommended.

2.8

engineered nanomaterial

nanomaterial (2.4) designed for specific purpose or function

2.9

manufactured nanomaterial

nanomaterial (2.4) intentionally produced to have selected properties or composition

2.10

incidental nanomaterial

nanomaterial (2.4) generated as an unintentional by-product of a process

Note 1 to entry: The process includes manufacturing, bio-technological or other processes.

Note 2 to entry: See “ultrafine particle” in ISO/TR 27628:2007, 2.21

2.11

nanomanufacturing

intentional synthesis, generation or control of nanomaterials (2.4) , or fabrication steps in the nanoscale (2.1) , for commercial purposes

2.12

nanomanufacturing process

ensemble of activities to intentionally synthesize, generate or control nanomaterials (2.4) , or fabrication steps in the nanoscale (2.1) , for commercial purposes

2.13

nanoscale phenomenon

effect attributable to the presence of nano-objects (2.5) or nanoscale (2.1) regions

2.14

nanoscale property

characteristic of a nano-object (2.5) or nanoscale (2.1) region

2.15

nano-enabled

exhibiting function or performance only possible with nanotechnology (2.3)

2.16

nano-enhanced

exhibiting function or performance intensified or improved by nanotechnology (2.3)
