Nanometer: A distance unit representing one-billionth of a meter, or one-millionth of a millimeter – roughly one-millionth the thickness of an American dime.
Nanotechnology: A collective term referring to the manipulation and control of materials at the nanometer scale. Physical phenomena are found at this microscopic scale that differs from those operating at the macroscopic scale.
Nanoscale: A size range from 1 to 100 nanometers, where many of the fundamental structures of biology are formed and where composite materials may take on distinctive characteristics.
Nanocomposite: A material composed of two or more substances, of which at least one has a nanoscale dimension, such as nanoparticles dispersed throughout another solid material.
Nanocellulose: Also called microfibrillated cellulose, this microscopic material is composed of nanoscale cellulose fibrils with a high length to width ratio. Typical dimensions are 5- 20 nanometers in width and length up to 2000 nanometers.
