We often talk about nanometers, so what does nanometer mean? Nanometer is a very small unit. Take meters for example. One meter is made up of billions of nanometers.


Nanotechnology is a general term for all activities carried out at the invisible and very tiny nanometer scale. It can be applied to various disciplines such as chemistry, technology, engineering and many other disciplines. The basic structure of nanotechnology is nanoparticles, which can be as small as 100 nanometers or less. The manipulation and design of matter at this scale (about 1/80000 of the width of a human hair) is the main research field of nanotechnology.
