What are some of the uses of nano-technology?

You can use them as catalysts to speed up the rate of the chemical reaction. Only the exposed surface area is essential. Therefore need much less of a material made of nanoparticles than a material made of bigger particles. Because the nano particles would have more surface area for the given volume. another example is using nano-particles in electric circuits because some of them can conduct electricity. So you could make really tiny computer chips. another use is in nano-medicine which is the use of nanoparticles in medicine. for example, scientists are currently researching how we can use fullerenes (made from carbon atoms) to deliver drugs around the body. since they are so tiny they think they can easily deliver drugs directly to the inside of our cells. you can also use silver nanoparticles for anti-bacterial properties for example you can infuse them into surgical masks and plaster's to kill bacteria and reduce the chance of infection.
