Nanobots: A Deadly Disease

The word nano derived from Greek meaning “dwarf”; a nano represent 10-9 (1m = 109 nm). Subsequently, nanotechnology is the study and manipulation of matter on a molecular scale, from 1 nm to 100 nm. The concept started out in 1959 with physicist Richard Feynman’s talks “There’s Plenty of Room at the Bottom,” in which he described a possibility which a scientist can control individual atoms. This process was dubbed nanotechnology by Norio Taniguchi of Tokyo University of Science. The field, at first, was hindered due to the inability to see matters at that small scale, until the invention of high tech microscopes, such as the atomic force microscope. Then, in 1885, Harry Kroto discovered a carbon based particle called buckyball and Sumino …show more content…
First, nanorobots can be used to destroy bad cells and prevent sickness. With cancer, the programmed nanorobots can be injected either directly to the infectious area or through the bloodstream if the area is hard to access. They, then, target the tumor, attach to it, and destroy it. Also, the nanorobots can “tour” around the body in the bloodstream and detect any potential dangers that could take years for current technology to find. Second, nanorobots can be used in drug delivery. Instead of subjecting to daily pills, a patient can have nanobots, which carry several doses of the drug, release the drug into the blood at a schedule time. This is quite useful to those with illnesses that require a complicated system of medical care and to those in the third world countries where medicine is a privilege. With nanotech, it’s possible to eradicate certain diseases or at least reduce their effect. Third, these machines are great assets in surgery; they allow precise surgical procedure, preparing cells and DNA while being controlled a surgeon somewhere else. There are many other ways nanotechnology can help improve the way medicine works, like sensor, imaging, and even cosmetic. Nanomedicine makes it possible for humans to live longer and healthier; an 80 years old man can still be part of the labor force. Not only is nanotech is important to the body, it is also important to the environment humans are living
