NanotechnologyThe nanotechnology works with materials and structures whose magnitudes are measured in nanometers, which is equal to one billionth of a meter. A nanomaterial has morphological properties smaller than one tenth of a micrometer in at least one dimension; in other words, considering that the materials must have height, width and length, one of these three dimensions is less than one-tenth of a meter divided by 1 million.

This applied science develops at the level of atoms and molecules. Chemistry, biology and physics are some of the fields of application of nanotechnology, which appears as a hope for the solution of various problems.

One of the first steps in the development of nanotechnology has been to understand the DNA as a key actor in the regulation of the organism’s processes. The moleculesTherefore, they prove to be decisive in life processes.

The nanomedicine, on the other hand, is the branch of the medicine that takes advantage of the knowledge of nanotechnology in procedures for health care. In this context, one of its potential applications is the development of nanometric-scale robots that are capable of entering the human body and completing different activities, such as the search for and destruction of cancer cells or the repair of fissures in the cells. bone tissues.

It is known as advanced nanotechnology to engineering of nanosystems that operate on a molecular scale. This discipline works with products created from a certain arrangement of atoms.

Critics of nanotechnology have mentioned various risks linked to its development, such as the potential toxicity of the new class of nanosubstances or the possible appearance of a so-called gray plague (where nanorobots would self-replicate uncontrollably until they consume all the living matter on the planet).

It is important to note that nanotechnology requires the participation of various fields of knowledge, such as the chemistry, molecular biology, computer science and medicine, among other sciences. Each one contributes the theory and practical work necessary so that the others can start from a base on which to investigate and develop, which is why this technology is called convergent. In other words, thanks to nanotechnology, the barriers that divide scientific knowledge are torn down, enhancing the complexity of the results.

Investing in nanotechnology

NanotechnologySeveral countries whose economies are going through a full developing economic, they invest considerable economic sums and specialized manpower in investigating the potential applications of nanotechnology. As mentioned above, nanomedicine presents tantalizing opportunities to the human being, especially when it is considered that it could improve various practices and procedures, such as diagnoses, cures, administration of medications and surgeries.

Worldwide, the number of laboratories that allocates important percentages to the investigation of this type of technology is around forty. On the other hand, around three hundred companies carry the prefix elder brother in their names, although this is not reflected in the product offerings available in the market.

With respect to computingIt is known that colossi such as IBM, Intel and NEC, among others, invest millions of dollars every year in their Research and Development departments, which affects the characteristics of the components they manufacture. Likewise, the governments of the most developed countries show a lot of interest in nanotechnology, and their monetary bets exceed by dozens those that can be made by the companies just mentioned.

But nanotechnology could improve many aspects of some industries traditional, which people do not always associate with the term technology; such is the case of the textile and footwear world, and of the food, health, automotive and building sectors.
