History and Future of Nanotechnology

Human dreams and imagination often give rise to new science and technology. Nanotechnology, a 21st-century was born out of such dreams. Nanotechnology is defined as the understanding and control of matter at dimensions between 1 and 100 nm where unique phenomenal enable novel applications. Besides human exposure to nanoparticles has occurred throughout human history, it has dramatically increased during the industrial revolution. The study of nanoparticles is not new. The concept of a “nanometer” was first proposed by Richard Zsigmondy, the 1925 Nobel Prize Laureate in chemistry. He coined the term nanometer explicitly for characterizing particle size and he was the first to measure the size of particles such as gold colloids using a microscope.
