"Nano" is a prefix from ancient Greek ("very small"), used since the early 20th century to illustrate the infinitely small. A nanometer is equal to one billionth of a meter (10 -9 meter), which is 1/50,000 the thickness of a human hair. The series of standards XP CEN/TS 80004 has been defining the lexicon since 2015. In particular, according to XP CEN/TS 80004-1 A nanomaterial is a material with an external dimension on the nanometric scale (1 nm to 100 nm) or with an internal structure or surface structure on the nanometric scale. A distinction must be made between nanomaterials of natural origin (erosion, sea spray, volcanic eruptions) and nanomaterials of anthropogenic origin, either manufactured...
