Made by: Karol Martinez MenaThe nanotechnology was firstly used by physicist Richard Feynman at an American Physical society meeting . He showed a process by which the ability to manipulate individual atoms and molecules might be developed and used one set of precise tools to build.
The Nanotechnology is the engineering of functional systems at the molecular scale. Usually this is called molecular nanotechnology or molecular manufacturing, because it will let us make most products stronger, smarter, cheaper, cleaner and more precise.
“Nan technological techniques include used semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nanoimprint lithography, atomic layer deposition, and molecular vapor deposition. However are extensions in the development of scientific advancements rather than techniques which were devised with the sole purpose of creating nanotechnology and which were results of nanotechnology research”.
If nanotechnology is going to revolutionise manufacturing, health care, energy supply, communications and probably defence, then it will transform labour and the workplace, the medical system, the transportation, power infrastructures and the military and advance technology like a cell phones, DVD, cameras and other things.
Advantage
New products that solve new problems in new ways are more difficult to foresee, yet their impact is likely to be even greater.
In the future, even weapons as small as a single bullet could pack more computer power than the largest supercomputer in existence today, allowing them to perform real time image analysis of their surroundings and communicate with weapons tracking systems to acquire and navigate to targets with greater precision and control.
We could develop a medical technology that for the first time would let us directly heal the injuries at the molecular and cellular level that are the root causes of disease and ill health.With the precision of drugs combined with the intelligent guidance of the surgeon's scalpel, we can expect a quantum leap in our medical capabilities.
Disadvantages
There is growing body of scientific evidence which demonstrates the potential for some nanomaterial to be danger to humans or the environment.The greater it’s surface area to volume ratio and the higher its chemical reactivity and biological activity.
Nanomaterials can damage access to the blood stream following inhalation or ingestion. At least some nanomaterials can penetrate the skin; even larger micro particles may penetrate skin and this can to cause acne, eczema, or severe sunburn. Once in the blood stream, nanomaterials can be transported around the body and are taken up by organs and tissues including the brain, heart, liver, kidneys, spleen, bone marrow and nervous system.
Finally the NANOTECHNOLOGY is very important, because while grew up the technology advances is a big benefit from the people, because this advantage produced that many things with difficult process will be more easy to do.
The people cant to avail of this advance especially for the cell phones that are fashion and necessary instruments. Nowadays are more small than before that appear the nanotechnology; at this moment almost all of the citizen of Costa Rica have one, in contrast someone don’t have, this is specially because they live in withdraw place.
