Nanotechnology, also called nanotech, is basically the technology that deals with the manipulation of matter on an atomic, molecular and supramolecular level. The earliest explanation of nanotech talked about the specific technological objective of manipulating molecules and atoms precisely for the construction of macroscale products, now called molecular nanotechnology.
Nanotech was described more broadly by the USA’s National Nanotechnology Initiative later. This institute defines it as the manipulation of matter which has at least one dimension of size between 1 and 100 nanometres. The origin of the concept that led to nanotechnology was first proposed by the eminent physicist Richard Feynman in 1959 in one of talks titled ‘There’s Plenty of Room at the Bottom’. Here, Feynman talked about the possibility of synthesis through the direct manipulation of atoms. The term ‘nano technology’ was first coined in 1974 by Norio Taniguchi.
