What is Nano?
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 a nanoscale, ranging from nanostructures, nanocoatings, molecular imaging, nanocircuits, nanosensors, and more. Existing applications range from sunscreens to waterproof mobile phones to life-saving medicines.
Although many people are aware that nanotechnology is very small, there is little discussion of how this emerging technology will change our everyday lives. Nanotechnology radically intervenes with our notion of what is natural. It may help to realize our dreams and significantly improve our lives, but it may also have unforseen downsides. Hence, there is an urgent need to have a public debate on the potential impact of these new technologies.
