Nanotechnology is the science and engineering of functional systems at the molecular scale. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up making complete, high-performance products. One nanometer (nm) is one billionth, or 10 −9, of a meter.

The second oldest abstract art and the oldest rock art is found at Blombos Cave in South Africa, dated to 77,000 years ago. [5] There are evidences that stone age humans around 100,000 years ago had an elementary knowledge of chemistry in Southern Africa, and that they used a specific recipe to create a liquefied ochre-rich mixture.

Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research. [9] Of the possible hazards, inhalation exposure appears to present the most concern.
