English

Etymology

Noun

nanoparticle (plural nanoparticles)

Any microscopic particle less than about 100 nanometers (nm) in diameter.
- 2005 February 22, Kenneth Chang, “Tiny Is Beautiful: Translating 'Nano' Into Practical”, in The New York Times‎^[1], →ISSN:
  Nanoparticles of various sorts are already found in products like sunscreen, paint and inkjet paper. More exotic varieties offer promise in medicine for sensitive diagnostic tests and novel treatments: the detection of Alzheimer's disease by finding a protein in spinal fluid, for instance, or nanoparticles that heat up and kill cancer cells.

Usage notes

In aerosol science, the term is often reserved for particles less than 50 nm in diameter; ultrafine particle is used for particles less than 100 nm in diameter.
