Nanotechnology represents the design, characterisation, production, and application of structures, devices, and systems by controlling the shape and size of the Nanometre scale.’ Thus, nanotechnology products are those derived from the phenomena and physicochemical characteristics occurring at the dimension of less than 100nm.
Nanoscience. According to the Royal Academy of Engineering (2004), the term nanoscience defined as following: Study of Phenomena and manipulation of materials at atomic, molecular, and macromolecular scales.
Molecular manufacturing is a term used to describe an emerging technology that is being developed to build large objects to atomic precision, quickly and cheaply, with virtually no defects. As it becomes more sophisticated, it promises to be an energy-efficient and environmentally benign way to make materials and textiles.
A bottom-up approach (self-assembly processes) is a term used to describe one of two ways to fabricate nanometre size elements of integrated electronic circuits.
