Nowadays the realm of Nanotechnology has getting much attention at globally. If the old days, bigger is much more preferable and fascinating, but now small has become much attention from most of the study. Most of definition on Nanotechnology revolves around the study and control of phenomena and materials at length scales below 100 nm. Beside that’s, Nanotechnology refers to the constructing and engineering of the functional system at very micro level/ atomic level. According to Bawa, R. Stephen B. Maebius, & e.t. al. (2005), Nanotechnology is the design, characterization, production, and application of structures, devices, and systems by controlled manipulation of size and shape at the nanometer scale (atomic, molecular, and macromolecular scale) that produces structures, devices, and systems with at least one novel/superior characteristic or property.
The credit for Nanotechnology would be expressed to Richard Feynman, a brilliant physicist which has presented the first ever Nanotechnology concept. In 1959 Richard Feynman suggested that it should be possible to build machines small enough to manufacture objects with atomic precision. In his lecture "There's Plenty of Room at the Bottom," Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Feynman described how the entire Encyclopaedia Britannica could be written on the head of a pin, and how all the world's books could fit in a pamphlet by a simple reproduction of the original pictures, engravings, and everything else on a small scale without loss of resolution. His talk is considered to be the foreshadowing of nanotechnology. In 1974, the term “nano-technology” is used by a Japanese scientist called Norio Taniguchi from Tokyo University of Science in a conference. Norio Taniguchi defines that "'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials
