Nanotechnology will allow advances in medicine in the near future. Nanomedicine, as it is defined, will help make the medical world more sophisticated. Doctors will soon be able to cure patients much quicker and with less pain. Also, the diseases that many people think aren't curable, may be able to be cured with the robots that help doctors use nanotechnology. This could mean that humans might have a longer life span and are able to stay healthy.
We are going to touch on a few sub-themes about nanomedicine in our nanotechnology chapter.
Eventually, in the future we might have devices that will "revolutionize medicine". There will be machines that go through our bodies in our bloodstream and do things we would never think are even imaginable such as zapping cancer cells and performing check-ups and minor surgeries.
One device that is already realized is the smart pill. This is an instrument the size of a pill that can be swallowed and tracked by another computer or electronic device. They have TV cameras to capture images of our insides that we can then see from the computer that is connected with the pill. Magnets can also guide the pills. This could help the pill locate tumors or polyps that could be harmful to humans.
