Nanotechnology argumentative essay

In medicine, nanotechnology has already been applied to the treatment of diabetes, the production of prosthetic limbs, and the improvement of life for the paralyzed, and many believe it is also the key to curing cancer and even immortality Using nanoscale science, phenomenal engineering, technological, medical, chemical, and informational feats are possible 1. The athletes on the other hand were approached through a focus group and one-on-one interviews One nanometer is about one twenty-five-thousandth the diameter of a human hair. Today's genetic screening can determine if a patient's genome contains specific aberrant genes, but can neither d It is the manipulation and use of materials and devices so tiny that nothing can be built any smaller. After that Richard Adolf Zsigmondy used the nanometer scale for particle size characterization in Nobel Laureate, physicist Richard Feynman is credited by the scientific community as being the first scientist to recognize the significance of the nanoscale range American Elements, n. But because nanotechnology is so broad and covers so many aspects of life, in this essay I will only discuss the promises in the health field A challenge for perfecting structures made by this kind of self-assembly chemistry is to. A material such as gold, which does not react with other chemicals at normal scales, can be a powerful chemical catalyst at nanoscales. New materials which can be scaled even at atomic size can be manufactured. Nanochemistry is an emerging field, and opportunities exist not only in the areas of theoretical and basic research, but also in applied research and commercial product development.

The battle to treat cancer has been stressful and harsh to patients. Carbon nanotubes have become a focus of special interest in recent years due to their ability to transport drugs to cells in a highly targeted manner Nanotechnology is the research and development of materials, systems, and devices with properties different from those found on the scale of molecules and viruses Patil et al.

However, there is a new breakthrough in combating cancer. Each of these has a huge effect on a system.

It is basically molecular engineering- frequently called chemical or molecular. Seeing a loved one die from cancer heartbreaking. Ethical, Legal and Moral Issues 6 a Nano-ethics 7 b Some ethical dilemmas faced by nanotechnology are: 7 c Component driven by nanotechnology. Some experienced nanochemists move into program management or administration, where they spend much of their time preparing budgets and schedules and obtaining funding, in addition to overseeing researchers and research programs. Not every startup company or new product line succeeds in the marketplace, so career flexibility, resilience, and a tolerance for risk are essential for the more cutting-edge lines of work. Nanotechnology holds pledge in the mission for ever-more-powerful computer systems and interactions gadgets. If perfected it could very well open the doors of possibilities allowing scientists the ability to deploy nanotech within the body or on an environmental level At first glance quantum technologies may seem unenchanting, however its study is a necessity for anyone wishing to intellectually advance beyond their current abilities. Soy proteins exhibit high loading capacity including electrostatic attractions, hydrophobic interactions and covalent bonding Some of the new agents use highly advanced technology utilizing nanoencapsulation that will improve the therapeutic index of the natural drugs. Such is the promise of Nanotechnology. However, all of the above examples of technologies are not considered nanotechnology, mainly because they do not use specific atomic instructions and actions to achieve desired properties and functions of the materials or products.

This is approximately ten times the size of an individual atom or ten hydrogen atoms laid side to side in a single nanometer.
