Nanotechnology is a type of science that deals with really, really small things like atoms and molecules. It is used to make and study materials that are only a few nanometers in size. These materials can have unique properties that are helpful in fields like medicine, electronics, and energy. For example, nanotechnology is used to make tiny medical devices that can deliver medicine directly to cells in our body or to create stronger and lighter materials for airplanes and cars.
