We build objects in our daily world from elements that we can see and feel. We use bricks or clay or steel.
Nanotechnology is the new science of building with objects at a molecular and atomic level.
Nanotechnology is important because it is the next level of creative science. It is common knowledge that modern science has come up against many walls or limitations that cannot be overcome with the present state of technology. For example, the limitations of computer speeds and hardware are a pressing problem today. These limitations can be overcome in future using this unique form of technology. One of the great promised advantages of Nanotechnology is the idea that it can be used to manufacture small robotic devices that can heal and clean the human body.
