What Is Nanotechnology?
Nanotechnology is the engineering of functional systems at the molecule scale. this covers both current work and concepts that are more advanced. Nanotechnology refers to the projected ability to construct items using techniques and tools being developed to make high performance products.

How nanotechnology works.
There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a light microscope. That world is the field of nanotechnology, the realm and nano structures. Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nano robots.In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nano scale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair. As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm. An atom's nucleus is much smaller -- about 0.00001 nm. Atoms are the building blocks for all matter in our universe. You and everything around you are made of atoms. Nature has perfected the science of manufacturing matter molecularly. For instance, our bodies are assembled in a specific manner from millions of living cells. Cells are nature's nano machines. At the atomic scale, elements are at their most basic level. On the nano scale, we can potentially put these atoms together to make almost anything., we'll learn about what nanotechnology means today and what the future of nanotechnology may hold.
Nanotechnology holds a great deal of promise for the world of medicine. It is likely that some of the first truly revolutionary changes noticeable in our everyday lives will be brought about by nano medicine.
the possibilities of nano medicine include nano formulations for efficient drug delivery, smart drugs which only activate when needed, engineered microbes which produce human hormones, and even "nano robots", which would move autonomously around the body acting as a boost, or a replacement, for our immune system, red blood cells, or many other biological systems.
Whilst many of these applications of nanotechnology as a long way off, there is a great deal of active research into medical technology - much of which is is not very far-fetched.
Researchers are investigating the possibility of launching an armada of millions of ultra-tiny nano devices into a patient's body for a range of purposes such as detecting cancer in its earliest stages, finding where cancer is located within the body by enhancing the way we image it, targeting anticancer agents specifically at malignant cells while minimizing their impact on healthy cells, and determining if these agents are actually killing cancer cells. Nanotechnology holds the promise of fundamentally changing the way in which cancer is diagnosed, treated, and prevented. For today's cancer patients, it is only a promise and it is not known if and when it might be realized but some early results are very interesting.
Nanotechnology R&D is typically undertaken by interdisciplinary teams involving various combinations of physicists, oncologists (both researchers and clinicians), chemists, biologists, mathematicians, computer scientists, radiation oncologists and imaging specialists, and different types of engineers. More and more articles dealing with nanotechnology are appearing in the medical literature as results from these R&D efforts emerge out of university, governmental, and industrial labs around the world. And, as you'd probably suspect, summaries of such efforts are appearing in the popular press and on television newscasts.
When you have many microscopes moving through our bodies repairing damaged cells and organs and wiping out many diseases it will save many lives and turn us into machine like humans because there constantly moving through our blood cells it may even replace biological blood. The nanobots will even eliminate disease and aging. Nanobots will search out damaged organs and cells and repair them. For example if a person gets hit by a bus or struck my lightning all damages can be fixed especially if the nanobots swim in and even replace biological blood then wounds could be replaced and repaired almost instantly. Limbs can be regrown. Memories and personalities can come back after terrible head trauma. Nanotechnology can add more years onto your lives. within 15 years we will be adding more years to your lives by every year that passes. In 40 or 50 years we will practically be immortal. But scientists say that adding nanobots wont make us any less human than we are today or were 500 years ago. It will only make our lives longer. Nanotechnology has just as many dangers as it does benefits the nanobots can create copies of itself and within 90 copies it can devour the body its in or all human if it becomes a nanobot plague. Nanotechnology has always been a double edged sword since we have had fire.
