* Nanotechnology, shortened to "nanotech", is the study of the controlling of matter on an atomic and molecular scale.
* Nanotechnology has the potential to create many new materials and devices with a vast range of applications, such as in medicine, electronics and energy production.
* The term “nano” is derived from Greek word “DWARF”, means small or tiny.
* Richard Feynman (a physicist of the California Institute of Technology) proposed the concept of nanotechnology in his famous lecture “There is Plenty of Room at the Bottom”.
* Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.
* The science of things are measured by a nanometer, which is one billionth of a meter or 10−9 of a meter.
1 nm = 10−9 m
Structures and properties
Properties of materials depend critically on the size of atoms constituting the material. If one can control the sizes of nanoparticles constituting the material , there are possibilities to assemble new nanostructured materials with unique or improved properties.
The trick is to manipulate atoms individually and place them exactly where needed, to produce the desired structure.
It is challenge for scientists to understand the size, shape, strength, force, motion and other properties while designing nanomachines.
Two main approaches are used in nanotechnology. In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control.
