Nanotechnology in Health

Résumé du document

Cancer occurs at the nanoscale with DNA damage. With these DNA damage we manufacture of different proteins.

If these proteins are necessary or important for the cell to where the body of the cell, the cell will die. But if the cell survives but if this protein Not necessary, it will not die. And if at best it improves basic protein, then there will be a new form of life. But if not essential protein is mutated, it can also be the emergence of new diseases. Or cancer can be a tumor over a billion cells. So instead of dealing with the problem in the present, we must identify at the source in the cancer cell is unique.

This is where we can use technology for early diagnosis before the cancer from spreading or the Alzheimer declares itself. Indeed, it has fleas combining computer, cell, genes and proteins, made by researchers to inspect the cells one by one. With this technology at the nanoscale (hence the name of nanotechnology). It could protect patients by identifying the earliest possible diseases. One can for example detect a cancer cell seven years before it develops. Whereas with the technologies associated with modern medicine, it uses imaging or magnetic resonance imaging (MRI) to identify cancer cells the size of a grape. Unfortunately, at this stage, there will be a tumor more than 30 generations of growth, ie more than one billion cells.

[...] Some proteins allow stem cells to differentiate into neural tissue. this is the way Stupp has designed a molecule that could do anything he wanted as provide support and stimulate at the same time the cell growth Selected nerve cells. Stupp manufactured molecules that could organize themselves into long filaments and solid so that these molecules have ends différentes.En Indeed, the first molecule, which is responsible for promoting the growth of nerve tissue, was made compatible with water. The second molecule hydrophobic tended to reach the other end molécules.Stupp and benefits of natural self-organization that is between the hydrophobic molecules in aqueous environments. [...]

[...] So nanotechnology will inevitably play a role. II-a) - Managing time is the place of administration of medicines In this area, we have Professor Bob Langer, who is a legend in research and in biotechnology. Indeed, he holds 400 patents. Many of these innovative works depart on the way to make space-time drug precisely. And his work mainly concerns cancer with applications for treating cancer, for which the precise administration of this product because huge benefits, wanting to kill cancer cells, substances are toxic. [...]

[...] To execute the mission strategy is as follows. We must first decide the size and shape of the bodies to fit the maximum in specific patient needs. For a leg, we consider the detailed structure of bone, cartilage, tendons, ligaments, blood vessels, muscles, nerves and skin that is a lot of complex things. Then this is the tissue engineer who manufactures the skeleton. It is responsible for determining the dimensions and the general structure of the body part has developed. [...]

[...] Another example of a polymer that is found naturally in our body is hydrogen. As the gelatine, the base may be the hydrogen liquids before they are transformed into solid. In the case where an implant body should be in liquid form would inject the hydrogen to fill existing voids in the tissue spaces. Then he would make solidification then under the supervision of a physician with a light that cause the fusion of hydrogen polymers. III-c)-Design and build a frame The frame must be used to support the growth of an organ replacement will be extremely variable due to the diversity of organ sizes, shaped by their structure and by the function they make. [...]

[...] It is amazing that nature can do all this while these processes are extremely complex. After building the frame we give a large part of the work nature. Thus we yield to the nature of control on architecture. To avoid this, researchers decided to build structures in three dimensions by pore. MIT Russell Giordano and his colleagues served industrial manufacturing methods by adapting it to the needs of engineer's tissues. To draw structures, engineer's cellular tissues have used a design and computer aided manufacturing. Progressed this way layer by layer. [...]
