3 Terms and Definitions
The terms and definitions defined in GB/T 30544.1-2014 and listed below apply to this document.
3.1
Nanoscale
The size range between 1nm and 100nm.
Note 1: This size range usually, but not exclusively, exhibits properties that cannot be extrapolated from larger sizes, for which the upper and lower limits are approximate. ||tt
||Note 2: The purpose of introducing a lower limit (about 1nm) in this definition is to avoid the default of a single or small cluster of atoms being considered a nano-object or nano
-structural unit when no lower limit is set.
[GB/T 30544.1-2014.Definition 2.1]
3.2
Nanotechnology
The application of scientific knowledge to manipulate and control matter at the nanoscale (3.1) to exploit size- and structure-related properties and phenomena that differ significantly from those of individual atoms, molecules or bulk materials.
Note: Manipulation and control include material synthesis.
[GB/T 30544.1-2014, Definition 2.3]
3.3
Nanomaterial nanomaterial
Material with any external dimension, internal or surface structure at the nanoscale (3.1).

Nanoscience and technology brings together the focus scientific issues in the nanoscale in multiple disciplines such as chemistry, physics, biology, and materials. It has gradually become a frontier research field that combines cross-cutting, leading and supporting functions. The application of nanotechnology in energy and environment, biomedicine, information devices and green manufacturing has become increasingly prominent, becoming a major source of transformative industrial manufacturing technology. In the past nearly 20 years, countries around the world have successively issued and implemented nanotechnology research and development plans. The application fields and scope of nanotechnology have continued to expand, and the supporting role for industrial technology has been significantly enhanced
A month ago, more and more nanotechnology was applied to industrial production. Scientists have already created nanoparticles, nanodots, nanotubes, nanowires, and nanosheets. These nanostructures have been used to manufacture field effect transistors, quantum dot light-emitting displays, biosensors, solar cells, potassium ion batteries, etc. Nanoparticle-based cancer therapies and nanostructured membranes for water purification have also been developed. Nanotechnology has gradually become a part of our daily lives, including many unexpected places, such as sunscreen, anti-wrinkle clothing and even golf clubs.
Although nanotechnology is well known to the public, there are still problems of hype, abuse and misuse of nanotechnology terms in the industry. Many products use the banner of nanotechnology but do not achieve the matching performance, and are even harmful to consumers, the corresponding companies and even the country. Due to the lack of standardized and authoritative definitions, classifications and naming methods, the role of nanotechnology and the authenticity of nanoproducts cannot be effectively judged from the industry to the company and even the consumer, which affects the credibility and vitality of the entire nanoproduct market. In order to promote the healthy development of the nanoproduct market and industry, the formulation of corresponding standards and specifications has been in progress, so it is necessary to formulate nanoproduct definition, classification and naming rules as soon as possible.

Nanoscale
nanustale
refers to the size range between 1m and 100m.
Note 1: This scale range is used to express properties that cannot be extrapolated to larger sizes in a normal but non-exclusive manner. For these properties, the lower limit of the scale is approximate.
Note 2: The lower limit (about 1 mm) is introduced in this definition to avoid the need to set a lower limit. A single or a small element is considered to be a nano-object or nanostructure unit.
