In the last few decades, science has been developed to an extraordinary standard cooperating with technology. Scientists by the beginning of the twentieth-century made a common knowledge that our universe is composed of fundamental structure blocks, atoms and molecules, that are extremely small, nearly a nanometer, a billionth of a meter. Nanotechnology describes the ways that scientists can now work with the actual molecules and atoms that make up our world. It’s basically a way of making things. However, the prefix “nano “, meaning one-billionth refers to the Greek language referring to dwarf. Science has begun to operate the building blocks and produce nano-sized devices that could be used in the medical field, food production, and environmental health, but the benefits are greater than the risks involved in the development of creating and taking nanotechnology to involve in our daily use. Genetically modified foods, ultra-powerful computer chips and non-staining, wrinkles-free clothing, cosmetics, sunscreen, anti-cancer drugs to targeted sites inside the human-body to detect them, nano-armor-lined turrets and doors for Humvees, Nano-foams and fiber to protect from chemical weapons and heat, all of these are nanotech products that’s are already a reality. Moreover, the technology has been used to create a variety of industries products, such as computer hard drives that store 1000 times more than the data than older version and special coating that keep the drives safe despite the risks. “What we can do in terms of controlling atoms and molecules is still very limited” said F.Mark Modzelewski, founder and executive director of the Nano-business Alliance, an industry trade group. The scientists foresee that “nanotechnology” in the future may free the world from its dependence on oil and create products such as self-repairing highways and computerized nano-particles to attack cancer cells. Moreover, there are more than 1,200 firms now around the world, which...
