A nanometer (nm) is one billionth of a meter (10⁻⁹ m). The 1 to 100 nm range is considered the nanoscale because materials within this size range often exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. This is due to quantum mechanical effects and a large surface area-to-volume ratio.
