Nanotechnology
CRITERIS D,E,F
Nanotechnology, the science of the extremely tiny as commonly known (one nanometer is one-billionth of metre), is an important emerging industry which is thought to reach a market of one trillion US dollars by 2015. It involves the understanding and control of atoms and molecules to create new materials with a variety of useful functions. It is the understanding and control of matter at the sphere of 1 to 100 nanometers (a sheet of paper is about 100,000 nanometers thick). Nanotechnology is a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to create microscopic devices and other microscopic things (example: Computer chips). It is a natural result of scientific development, our ability to understand and manipulate matter at smaller and smaller levels. Just as computers have gone from bulky, room filling machines to tiny laptops and palmtops. Nanomaterials are now used in a variety of products, including sporting goods, cosmetics and electronics. The fact that unusual physical, chemical, and biological properties can emerge in materials at the nanoscale makes them particularly appealing for medicine. Scientists hope nanoparticles will be able to improve the effect of drugs and gene therapy by carrying them to the right place in the body and by targeting specific tissues, regulating the release of drugs and reducing damage to healthy tissues. They also envision the possibility of implantable nano devices that would detect disease, treat it and report to the doctor automatically from inside the body. Let us look at the uses of nanotechnology more closely.
The uses of nanotechnology
Nanotechnology creates stain repellent clothing. The nano-fibres prevent staining of clothing, the nano-fibres are 10 to 100 nanometers in size and these prevent staining substances from being absorbed in the clothes. One of the most important use of nanotechnology is that it can
