The 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
- Atomically engineered food and crops resulting in greater agricultural productivity with less labour requirements.
- Nutritionally enhanced interactive ‘smart’ foods.
- Cheap and powerful energy generation.
- Clean and highly efficient manufacturing.
- Radically improved formulation of drugs, diagnostics and organ replacement.
- Interactive ‘smart’ appliances; and increased human performance through convergent technologies.
- We could inexpensively make very strong and very light materials.
- We could make surgical instruments of such precision and deftness that they could operate on the cells and even molecules from which we are made -- something well beyond today's medical technology.
- 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.

Nanotechnology is a gig word and gig world , but really this tried to make easier everything in nowdays is so useful the high tecnology and this is coming for provide facilities in factories ,in foods ,in farmers,the machines are coming to remplace the handwork , and each time is so clear how this kind of technology help us and is changing each time making the gig things in smallest things.Really enjoy read about this article nanotechnology is like a smart brain I like that way .
The technology is a good way of help people.The nanotechnology is a form of medice in which the more important is that human being find the future in this kind of medice.According to studies nanotechnology is good for our health but when this kind of technology be accepted will be probable that everybody to use it.
karol this was very important because many doctors say different thing abot now i know more abot it and this topic is very interesting to people nowaday
your topic is fine. Everybody know that technology is a benefit for us. Without technology maybe we should make all our works in a hard manner; so that, I believe that there is nothing bad with technology.
The technology everyday change and modernized all concepts,nanotechnology is interesting in the topics that can forey to make and invent medicine or machines that can helps sick people.
"nanotechnology" might inprove our quality of live because all thing will be more easy to find and also the size will be cofortable to the comsumer but with it, but it also mean the end of the traditional thing and with the termination of some important thing of our cultures.
This topic is so very important actually because the most of the thing need of the nanotechnology, is so able in the most things of the human.
