Nanotechnology - Assignment Example In the 1980s, K. Eric Drexler popularized the word nanotechnology by talking about building machines on the scale of molecules like robot arms, motors, and even computers into those far smaller than a cell. In the traditional sense, nanotechnology means building things from the bottom up, with an atomic precision. This theoretical ability was envisioned in the early 1959 by the renowned physicist,  Richard Feynman. A layman’s understanding of nanotechnology has evolved considerably since the progression of mainstream films like Star Wars and Science Channel documentaries, whereas before, these concepts were little known to the public and were considered to be of science fiction and in the far distant future (Johnson 103). It represents the manufacturing system which has the ability to make enough manufacturing systems implying factories can be built rapidly, cleanly and cheaply. This enables means of production to reproduce exponentially, so that in just a few weeks few nanofactories conceivably can become  billions. Nanotechnology offers great potential for benefit to humankind, and also brings severe dangers. While it is appropriate to examine carefully the risks and possible toxicity of nanoparticles and other products of nanoscale technology, the greatest hazards are posed by malicious or unwise use of molecular manufacturing. CRNs focus is on designing and promoting mechanisms for safe development and administration of MM effectively. This technology is suspected to cause cancer. Nanoparticles are tiny enough to penetrate cell membranes and defenses and they are able to cause problems by interfering with normal cell processes. Researchers at the University of Massachusetts record that such nan oparticles are presently in use in cosmetics, electronics, and chemical manufacturing, and others industries. Pacheco and her colleagues examined how two different types of nanoparticles could damage DNA in the MCF-7 line of the breast cancer cells.
