nano-

a combining form with the meaning “very small, minute” (nanoplankton; nanotube); in the names of units of measure it has the specific sense “one billionth,” or 10⁻⁹ (nanomole; nanosecond), and can refer specifically to a scale measured in nanometers (nanotechnology).

Also, nanno-.

[comb. form representing Greek nânos, nánnos dwarf]

nano-

1. A prefix that means:

2. One billionth, as in nanosecond, one billionth of a second.
