Nanotechnology, the manipulation of matter at the atomic and molecular scale to create materials with remarkably varied and new properties, is an expanding area of research with much potential in many sectors, such as healthcare or construction and electronics. In this article , I will briefly explain to you some parts of this complicated subject. In the medicine, Nanotechnology pledges to revolutionize drug delivery, gene therapy, diagnostics, and other areas of research, development and clinical tests. The ability to manipulate structures and properties at the nano scale in medicine is helping a lot of doctors to do things they couldn't do in the past. Manipulating DNA involves the manipulation of individual genes, or the molecular…show more content…
Recent years have seen a huge jump in the amount of studies that show the variety of medical applications of nanotechnology and nanomaterials. In this article we have seen just a small cross-section of this vast field. However, there is more challenges to overcome, the greatest one appear to be how to measure up the production of materials and tools, and how to lower expenses and timescales. In addition, another challenge is to how to secure public confidence and convince them that this rapidly expanding technology is safe. And until now, there is no progress in that area. There are some people who think that the concerns about nanotechnology are in a way over-exaggerated and fictional. They state that just because a material is nanosized, it does not mean it is dangerous, indeed nano particles have been around in our planet since it was created, occurring naturally in volcanic ash and sea-spray, for instance. As results of human activity, they have been present on earth since the Stone Age. But, there are also nervous and worried parties, who said that while the pace of research goes faster, and the market for nanomaterials grows ,it appears that not enough effort is being done to discover their real
