The term “Nano” is a measurement and not an object and is a direct and sole reference to the scale of the molecules in the specific material. One “nanometre” (nm) equals one millionth of a millimetre.
Examples of nano-materials in nature that exists without any human modification are the water repelling structures on a lotus leaf, a gecko’s ability to walk on glass, the UV protection in the edelweiss plant, anti reflective eyes of moths, and the fact that milk is nano-protein particles suspended in water.
The raw materials used in Elements Air and Elements Earth are certain chemical elements from the Periodic Table and occur naturally in nature and consist mainly of SiO2.(Silicon Dioxide/Silica)
