Nanotechnology

Nanotechnology is like a really tiny kind of technology. It's so tiny that you can't see it with your eyes! But it can do really cool things. Scientists use nanotechnology to make things that are smaller and lighter, like in airplanes or cars. They also use it in medicine to make tiny machines that can help doctors find diseases in our bodies and even help fix them.
