We are all now on the Fantastic Voyage
Remember you Fantastic Voyage '-? Sci-fi film in which researchers reduced the submarine and crew, they are injected into a dying man, and saved him from certain death, before they changed to more adventures
Harry Kleiner written in 1966 and novelized the Bantam paperbacks six months later, Isaac Asimov, it spawned an animated TV series, as well as the Salvador Dali painting. It is now about 40 years later, he saw the practical applications in space medicine and cancer, and probably more prosaic areas such as materials science.
Today it is called "Nanotechnology" in this short series of articles exploring how we can begin to affect the world around us. It starts to connect physicians and building science.
Nanontechnology short
Nanotechnology deals with the science is very, very small structures, usually less than 100 nanometers in diameter. On a nanometer being 1 billionth of a meter, you'll have ideas on how to run this country as imagining that a diameter of 1 meter with 1 billion apple pips (seeds) inside it. Or, looked at another way, measuring the relationship between a meter and a nanometer is the same as between Earth and an apple.
for mathematical purists among you, 1 nm = 10 -09 m, or 1/1, 000 million
Einstein could not imagine such a building of railway wagon in his mind, as this length, width and height of 1 nm and then fitting it within a few hundred molecules of hydrogen.
For scientists and technologists to have a special interest, because in this size materials exhibit unique properties compared not only with ordinary sized bulk materials, but their molecules. In fact, they take advantage of properties that no single molecule or molecular structure of the exhibition.
For example, if we could see the gold nanoparticles deposited on the surface appears purple rather than bright and 'gold' that we recognize today.
Again, if you can imagine such molecules have very little to the atom nucleus with electrons revolving around a lot of this, all together the power of attraction, then you will get some idea of the scale of things to do.
Another example of special interest to scientists and technologists who are currently working or considering working in this area is that the titanium dioxide (titania). It is used to give color to a very white, opaque appearance. But nanonised Titania is quite clear.
Nanomedicine
drug discovery, drug delivery, and further miniaturization of the three areas in which the drug has joined our Fantastic Voyage. Long-term, in-vivo diagnosis and more targeted therapy without the side effects are on the horizon. Being able to search for drug targets in the cell rather than multi-cellular or tissue basis can be much more precise. Biosensors and molecular probes allows cellular processes to review and remedy aimed at the development of molecular targets.
New processing techniques already allow medication to be put inside the nanoparticles, such as carbon nanotubes or silicon. It also can keep the antibodies bind the drug, allowing smaller doses to be delivered directly to target tissues. Various nanoparticle drug formulations are already under investigation in animal models and early clinical studies in humans.
treatment of cancer and diabetes
Use these nanobots, or vehicles for the transport of treatment, radioactive generators already injected. Going directly to the infected tissue to give a small dose of radiation to treat cancer without any unpleasant side effects of radiotherapy.
By encapsulating the cells in the pancreas nanoparticles can be alive to secrete insulin antibodies without being attacked. This is not a cure for diabetes, but not avoid unpleasant injections, delivering insulin in a natural way.
brain tumors and Space Medicine
Neuroscientists develop nanoparticles to cross the blood brain barrier and may be the treatment of brain tumors within a few years. In the meantime, NASA conducts remote diagnostics and treatment for space travelers, such as radiation damaged cells. As Cecilia Haberzettl, founder and president TechnoMed strategic partner, recently wrote in Nanotechnology
"When a cell is damaged by radiation express different proteins on its surface. Nanobot to detect these proteins, and then fix the cell, either by giving antioxidants or enhance the natural repair mechanisms of DNA from some techniques have yet to be determined. Or, if the damage is severe, nanobot can trigger cell death. All this could happen, and astronauts are in space, while avoiding communication delays due to the distance from Earth. "

of treating people treating the building where they live, how nanotechnology is used in materials science and how the Greek entrepreneurial scientist has developed products that protect the surface from stains, mold and fungus. Personally admits Bill Gates, founder of Microsoft, the innovative nature of their work, they are undoubtedly delivering top nanotechnology inventions and technical excellence to improve and add value to a wide range of everyday products.
Look at the following article to learn how this small company is experiencing growing international growth delivering tremendous progress and technical excellence in surface protection.
