3.1 Introduction
Identifying problems as challenges and involving in solving them is the nature of innovators in society. In this process, the technology is used as a tool. Most of the current problems of human beings related to basic needs, advanced wants, and dreamy desires can be solved using twenty‐first century technologies, which include nanotechnology (NT) and information communication and computation technology (ICCT) [1]. Though the word NT is first used by a Japanese Professor Norio Taniguchi of Tokyo University of Science in 1974 conference to describe the characteristics of a thin film of the order of a nanometer, the idea is originally proposed by Richard Feynman in 1959 in his speech on there's plenty of space at the bottom at the American Physical Society meeting. Thereafter in 1981, Eric Drexler
