The essence of invisible technology is that it’s present in our everyday life. From a cash register to your computer.

Nanotechnology is the manipulation of matter at nanoscale. The earliest and most widespread description of nanotechnology refers to the particular technological goal of precisely manipulating atoms and molecules for the manufacture of microscale products.

In the future, nanotechnology will be the essence of our life, we will have thousands of robots working on our body capable of healing us of all the damages we have.
This would promote a great social advance.
It can also have many uses in the creation of new materials and a more precise production improvement.

These are some of the uses of nanotechnology already implemented:

• Alternative energy production (hydrogen energy, fuel cells, energy saving devices).

• Administration of medicines, especially to combat cancer and other diseases.

• Quantum computing, semiconductors, new chips.

• Security. Microsensors of high performance. Military industry.

• Various industrial applications: textiles, sports, materials, automobiles, cosmetics, paints, construction, food packaging, flat screens.

• Environmental pollution.

• Aerospace services: new materials, etc.

• Molecular manufacture.

Nanotechnology will promote the production of graphene, a lightweight, resistant, flexible and impermeable material. It can have a thickness of up to two atoms. A square metre of graphene can hold a cat (4kg), its weight being less than one of the cat’s whiskers.

Advantages:

The use of molecular nanotechnology (MNT) in production and manufacturing processes could solve many of the current problems. For example:

• Water scarcity is a serious and growing problem. Most water consumption is used in production and agriculture systems, something that the manufacturing of products through molecular manufacturing could transform.

• Infectious diseases cause problems in many parts of the world. Simple products like pipes, filters and mosquito nets could reduce this problem.

• Information and communication are useful tools, but in many cases they do not even exist. With nanotechnology, computers would be extremely cheap.

• Many places still lack electricity. But efficient and inexpensive construction of lightweight and strong structures, electrical equipment and energy storage devices would allow the use of solar thermal energy as a primary and abundant source of energy.

• Environmental wasting is a serious problem all over the world. New technological products would allow people to live with a much lower environmental impact.

• Many areas of the world can not quickly assemble a manufacturing infrastructure at the level of the more developed countries. Molecular fabrication can be self-contained and clean: a single box or a single suitcase could contain everything necessary to carry out the industrial revolution at the village level.

• Molecular nanotechnology could manufacture cheap and advanced equipment for medical research and health, making the availability of more advanced medicines much greater.

 

Disadvantages:

Molecular nanotechnology is such an important advance that its impact could be comparable with the Industrial Revolution but with a remarkable difference - that in the case of nanotechnology the enormous impact will be noticed in a matter of a few years, with the danger of being the humanity unprepared by the risks that such an impact entails. Some considerations to consider include:

• Important changes in the structure of society and the political system.

• The power of nanotechnology could be the cause of a new arms race between two competing countries. The production of weapons and devices of espionage could have a much lower cost than the present.

• Cheap production and duplication of designs could lead to major changes in the economy.

• Overuse of cheap products could cause significant damage to the environment.

• The attempt by the administration to control these and other risks could lead to the adoption of excessively rigid regulations that in turn could create a demand for a black market that would be as dangerous as unstoppable because it would be very easy to traffic with small and very dangerous nanomade products .

Simple solutions will not succeed. It is unlikely to find the right answer to this situation without first entering into a meticulous planning process.
