They are, as their name suggests, microscopic particles with a dimension less than 100 nanometers (the equivalent of a thousand atoms).
As you have already seen, today the field of nanoparticles is experiencing a great expansion in terms of scientific research thanks to its potential to be used in sectors such as medicine masterbatch manufacturer, electricity, cosmetics or optics, among other areas.
The science that studies and works with nanoparticles is nanotechnology. Thanks to this new technology, researchers can work with and manipulate molecular structures and their atoms, managing to evolve in many aspects that will allow an improvement in the lives of many people.
But like all science and all technology, they have different varieties and types to be used in different studies.
