Advantages And Disadvantages Of Nanotechnology

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
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
What happens, for example, to insoluble nanoparticles? If they can't be broken down, there is a danger that they will group and damage healthy organs. Nanomaterials comprising inorganic metal oxides and metals are thought to be the ones to pose a risk in this area. Also, because of their high surface area to mass ratio, nanoparticles are extremely reactive, and may for instance, trigger unspecified chemical reactions, or by bonding with toxins and allowing allow them to enter some body cells that they would usually can't enter. The Research Councils are not giving enough priority to investigating the safety of nanotechnology, much more research is needed to the safety of this particular technology.

It would then appear whether true or not, the real danger and risk that nanotechnology poses to human health must be investigated. Most nanomaterials are harmless to human beings, but, when a technology advances too quickly, knowledge and communication about its danger needs to be in pace so it won't otherwise harm the human kind, especially if it is also to secure public confidence. Until we truly know the dangers of this astonishing technology, we should keep investigating about this technology until we fully understand its benefits so we can use the most of it to help the human beings advance much
