It is also known as molecular nanotechnology. Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Nanotechnology is manipulation of matter on an atomic, molecular, and supramolecular scale.
It includes the fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, molecular engineering, etc. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in nanomedicine, nanoelectronics, biomaterials energy production, and consumer products.
Nanotechnology will play a big role on all of our lives in the very near future in everything ranging from clothes to medicine.
