1 nanometer is 1 billionth of a meter, or about 1/100,000th the thickness of a human hair. Nanotechnology refers to science and technology that creates materials, devices, or systems that exhibit new or improved physical, chemical, or biological properties by manipulating, analyzing, and controlling materials in the nanometer-sized range. Controlling the arrangement of atoms and molecules in the 1 to 100 nm range has a significant impact on the properties of materials, devices, and systems, and enables the production of new materials and advanced products with special functions using nanotechnology.
