International Gold Nanoparticles Definition
International gold nanoparticles are defined as microscopic particles of gold with diameters ranging from 1 to 100 nanometers (nm). These particles are composed of a core of gold atoms surrounded by a shell of organic molecules, known as ligands. The ligands stabilize the gold nanoparticles and prevent them from aggregating.
Gold nanoparticles have a unique set of optical, electronic, and chemical properties that make them useful for a variety of applications. For example, gold nanoparticles can be used as catalysts, in biosensors, and in nanomedicine.
The international gold nanoparticles definition was developed by the International Standards Organization (ISO) in 2010. The ISO definition is intended to provide a common reference point for researchers and manufacturers of gold nanoparticles.
The ISO definition is based on the following criteria:
* Size: The diameter of the gold nanoparticles must be between 1 and 100 nm.
* Shape: The gold nanoparticles must be spherical in shape.
* Surface chemistry: The gold nanoparticles must be coated with a layer of organic ligands.
The ISO definition of international gold nanoparticles is a valuable resource for researchers and manufacturers of these materials. The definition provides a common reference point that can be used to compare different gold nanoparticles and to ensure that they meet the desired specifications.
