Nanotechnology: The Uses of Nanotechnology

what are some examples of nanotechnology

Those huge heavy television sets are history now thanks to the evolution in transistors. We all know the cosmetic range from L'Oreal which has brought the fantastic wrinkle-free creams for the aged women who want to look elegant and gorgeous. They can also see applications in regeneration of human tissue, bone and cartilage, and even as a way to develop tinier and more powerful microprocessors for use in computers and consumer electronics. Mechanical utilizations of nanotechnology Nanotechnology works in two different ways, the world of molecules and the world of atoms. The social advantages include, reproducing extinct animals and plants, safe and space travel, higher education, molecular food synthesis, to mention a few.

Just as anti-social behavior is irresistible to a certain percentage of the population — as evidenced by the number of computer viruses in existence — irresponsible people and groups are likely to make self-replicating nanofactories, thereby increasing the possibility of disaster. Organizations such as of Australia, Individuals Tending Toward Savagery in Mexico, and the in America actively oppose any further development of nano-scale projects. In other words, materials can have different physical properties on the nanoscale even though they're still the same materials! Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars maintains an inventory of nanotechnology-based consumer products currently on the market. Nanosolar by printing nanoparticles on spools of cheap metal foil. We often see the metal detection devices at airports, which are, used to scan the passengers.

These methods are used today to produce a wide variety of useful chemicals such as pharmaceuticals or commercial polymers. This may result in solar cells that generate electricity as cost effectively as coal or oil. Combined with refined processes such as electron beam lithography and molecular beam epitaxy, these instruments allow the deliberate manipulation of nanostructures, and led to the observation of novel phenomena. By storing the molten salt overnight you can keep making power even when the sun is down. In science it means one billionth 10 to the minus 9 of something, thus a nanometer nm is is one billionth of a meter, or 0. The researchers also found there was another benefit in using these nanoparticles, they could define where the nanofibers grew and by correct placement of the nanoparticles they could grow the nanofibers in a desired specific pattern: an important feature for useful nanoscale materials. Nanotechnology applications are used in medicine, chemistry, the environment, energy companies, and communication.

However, there are certainly intriguing possibilities for their use, especially within human bodies. In medicine, it promises to revolutionize drug delivery, gene therapy, diagnostics, and many areas of research, development and clinical application. These concerns may be a thing of the past, however, if a promising new type of solar cell utilizing nanotechnology pans out. Advancements associated with quantum mechanics e. If you stepped into your living room, what you'd see around you would not be chairs, tables, , and your family but , molecules, proteins, and cells. Much speculation exists as to what new science and technology may result from these lines of research. You've probably looked at amazing photos in science books of things like dust mites and flies photographed with.

Also, because of their high surface area to mass ratio, nanoparticles are highly reactive, and may for instance, trigger as yet unknown chemical reactions, or by bonding with toxins, allow them to enter cells that they would otherwise have no access to. Now thread it over another molecule made from a rod of atoms, which has slightly negative charges at its two ends. Despite the great promise of numerous nanotechnologies such as quantum dots and nanotubes, real commercial applications have mainly used the advantages of colloidal nanoparticles in bulk form, such as suntan lotion, cosmetics, protective coatings, and stain resistant clothing. The difference is that these objects are molecules. Bioactivatable nanoparticles that change properties in response to factors or processes within the body act as dynamic reporters of in vivo states and can provide both spatial and temporal information on disease progression and therapeutic response. Yet the nanoscale—the world where atoms, molecules atoms joined together , proteins, and cells rule the roost—is a place where science and technology gain an entirely new meaning. One problem is that tiny particles can be extremely toxic to the human body.

Nanotechnology will affect every aspect of our lives, from the medicines we use, to the power of our computers, the energy supplies we require, the food we eat, the cars we drive, the buildings we live in, and the clothes we wear. Today nanotechnology is being applied to every area of our lives. How virtual reality can shrink scientists down to nano dimensions. These products use nanostructure in their building materials to give them enhanced and better performance. The researchers hope this new method will greatly improve the delivery of drugs to treat cancer, heart disorders and Alzheimer's disease. It is because of this factor that you can prevent skin aging by using the products which have the nanotechnology built into it.

The developed pattern is then imposed on successive layers the pattern transfer stage to develop desired three dimensional structural characteristics. However, it becomes dominant when the nanometer size range is reached. According to , nanofactories will include machine systems for engineering and technical work which, in turn, will manufacture computers that are thousands of times more powerful and inexpensive than current computers. This webpage includes information on the use of nanotechnology in the fight against cancer, including the use of nanotechnology in developing unique approaches to the diagnosis and treatment of cancer.

Recent years have seen an explosion in the number of studies showing the variety of medical applications of nanotechnology and nanomaterials. Nanomachines One of the most exciting areas of nanotechnology is the possibility of building incredibly small machines—things like , switches, , or —from individual atoms. Already clinically established as contrast agents for anatomical structure, nanoparticles are being developed to act as molecular imaging agents, reporting on the presence of cancer-relevant genetic mutations or the functional characteristics of tumor cells. Milk is an example of nanotechnology. Popular Science, November 1960, p. Nanofibers Nanofibers are fibers with diameters of less than 1,000 nm.

These new brain cells would process information much faster than a biological brain, just as an artificial limb can be stronger than a human arm or leg. Sunscreens and some anti-aging products are the main cosmetic products on the market currently being made using nanotechnology. These are mostly frivolous exercises, designed to wow people with nanopower. The graphite in pencils is a soft form of carbon. It turns out there are some very interesting things about the nanoscale. Nanotechnology is the technology of building devices, such as electronic circuits, from single atoms and molecules. An hexagonally close-packed cluster of tubular pores end view is shown in the foreground.
