Nanotechnology is an emerging field of science that deals with the manipulation of structures on an atomic and molecular scale – the size of one billionth of a meter. Nanotechnology is often seen as a trend in material science, but has much deeper implications.
Nanotechnology, or more precise nanotechnologies, is an umbrella term for various techniques that scientists use to operate on the very small nanoscale, ranging from nanostructures, nanocoatings, nano-encapsulation, nanocircuits, nanosensors, nanoparticles, and more. Existing applications range from sunscreens, from mobile phones to airplanes to medicines.
Although many people are aware that nanotechnology is very small, there is only little discussion on how this emerging technology will change our everyday lives. Nanotechnology radically intervenes with our notion of what is natural. It may realize the dreams people have of themselves and significantly improve our lives, but may also have its downsides. Hence the urgency to have a public debate on the impact of nanotechnology on our lives.
