Nothing is for certain. It is being developed for use in healthcare. Well, something called Qdots to be more precise. The full name being Quantum dot, these tiny wonders emit rays of light in a variety of colors. There is a possibility that one day they can be released inside the body to test for cancer. The dots would attach to tumors and flash their lights until the doctors found them. It would be beneficial to cancer patients to have their tumors located at the earliest possible time, when they are quite small. It would save lives. There are other treatments that nanotechnology is already used for.
Other things aside from health care are possible. Advances in computer technology. Robotics. Energy. Global Positioning systems that are faster and more accurate. DNA
fingerprinting that is quicker. There is a special type of clothing invented using silver nanoparticles. Guess what? You don't have to wash it! You just wipe the dirt off. The nanoparticles keep dirt from staining the clothing.
This is an exciting time in the new field of nanotechnology. There's a lot of things that could be improved using it. One day, people will look back and say, " Wow, their computers took, like, five seconds to load! Way too long! How did they stand waiting?!" or something like that. Our computers will be made smaller too. People in the future will ask their grandparents how they put up with having such big computers, and will think about it the way we think about people having one room for the computer like they used to. Won't that be the day?
