Once limited to a role in science fiction books and movies, nanotechnology is getting ready to invade our lives in beneficial ways. Nanotechnology is the study of, or use of, extremely small things, often at the atomic level. How small? One nanometer is a billionth of a meter, or, in other words, there are 25,400,000 nanometers in an inch. Obviously, we cannot see these things with the naked eye (or even a basic microscope).
Scientists have discussed how nanotechnology could impact medicine for years. Or, at least, they have done so in theory. Nanobots could, in theory, perform surgical tasks in a human body; sort of a real version of the 1966 movie, Fantastic Voyage. Nanotechnology could also assist in prosthetics, medical tools and processes. The possibilities are truly endless.
But, some uses of nanotechnology have left the realm of “theory” and moved into that of “reality.” One recent example is an experiment conducted using an injection of magnetic nanoparticles in place of traditional anesthetic for an ankle block. The study was successful, demonstrating that this process does work (at least in rats). By identifying specific areas in which nanotechnology may benefit us, these researchers are helping other scientists refine realistic use of the nanotechnology.
