International Gold Nanoparticles Definition
Gold nanoparticles (AuNPs) are small particles of gold with a diameter of less than 100 nanometers (nm). They are typically spherical in shape and have a variety of applications in electronics, medicine, and other fields.
The International Organization for Standardization (ISO) has defined gold nanoparticles as “gold particles with a diameter of less than 100 nm.” This definition is based on the fact that the properties of gold nanoparticles change significantly as their size decreases. For example, the melting point of gold nanoparticles decreases as their size decreases, and the optical properties of gold nanoparticles change as their size and shape change.
The ISO definition of gold nanoparticles is important because it provides a common reference point for researchers and manufacturers. This definition helps to ensure that different research groups are talking about the same thing when they discuss gold nanoparticles, and it also helps to ensure that manufacturers are producing gold nanoparticles with the same properties.
Gold nanoparticles are a promising new material with a wide range of potential applications. The ISO definition of gold nanoparticles is a valuable tool that will help to accelerate the development of these applications.
