Origin of 'nano-'
Main points about word origin
- The prefix 'nano-' comes from the Greek word 'nanos,' meaning dwarf, denoting very small size.
- 'Nano-' was first popularized in the 1970s as scientists began studying materials at the atomic level.
- The term 'nanotechnology' was introduced by K. Eric Drexler in his 1986 book 'Engines of Creation.'
The prefix 'nano-' is derived from the Greek word 'nanos', meaning 'dwarf'. It was first adopted into the International System of Units (SI) in 1960 to denote a factor of 10^-9. As science and technology advanced, especially in the late 20th century, the term gained prominence with the rise of nanotechnology. This refers to the manipulation of matter on an atomic, molecular, and supramolecular scale, which has enabled significant advancements across various fields including materials science, electronics, and medicine. The association of 'nano' with minuscule sizes has made it a vital part of modern scientific terminology.
