The accepted scientific definition of the term “nano-molecular” is any material with an atomic/molecular level ranging from one nanometer (nM) to 100 nM [1 nM = 1 Billionth of a Meter; or approximately 1/80,000 the diameter of a human hair].To assist in understanding the scale at which nano-molecular/atomic reactions occur, XUREX has provided an interactive measurement scale titled "Scale of Things" (See "Scale of Things" Link on the Top of the Technology Page) to aid in visualizing and understanding the scale of where true nano-molecular really occurs, both man-made and natural.
