You probably know from your science classes that atoms are the building
blocks for all matter in our universe. You and everything around you are made of
atoms. For fun some scientists have created from atoms - a nano MAN called IBMman.
Nanotechnology may have its biggest impact on the medical industry. One day, robots could be smaller than human cells. These microscopic machines, called nanorobots, could travel through the bloodstream and kill unwanted bacteria or viruses.
Researchers and engineers are now designing the basic building blocks for these futuristic machines. Take a look at how a nanorobot might work.
