nanoparticle (rus. наночастица) — an independent solid phase object with a distinct boundary sized between 1 nm and 100 nm in all three dimensions.


Nanoparticle is one of the most common terms denoting an individual ultradisperse object. This term has almost the same meaning as earlier used terms such as colloid particles, ultradisperse particles, but differs from them due to the precise definition of dimension scale. Solid particles sized smaller than 1 nm are usually referred to as clusters, and larger than 100 nm – submicron particles.
