Nanotechnology is expected to become a fundamental technology in the future. This paper describes the trends in nanotechnology and its future prospects. First, the history of nanotechnology is reviewed. Next, the definition of nanotechnology is reconsidered from the viewpoints of fabrication, size, materials, and morphology, leading to a simple classification of the wide range of varieties of nanotechnology. This is followed by the most important section o this paper, explaining the application of nanotechnology in the fields of electronics, bionics, mechatronics, energy, and environment. The emphasis in this section is on areas of application where Toshiba is making efforts to develop new technology.
