But what does the nanotechnology mean? It is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications.
The word nano is a scientific prefix that stands for 10-9 or one-billionth.
Nanotechnology is a group of intensively developing industries that utilize the structure of materials whose size is close to the size of separate molecules and their organized units or supramolecular structures. Nanoscience is the research of phenomena and properties of materials at the nanometer level. Nanotechnology uses the acquired knowledge and skills for designing new materials and structures with new and sometimes unusual properties.
The nanotechnology is applied in many different areas, such as medicine (diagnostics and therapy of tumors; implants – artificial joints, valves, replacement of tissues, etc.), food industry (smart multifunctional packaging to increase the shelf life and quality of food, effective nutritional supplements, etc.), electronics (high-capacity recording media, imaging devices with high resolution, high-capacity batteries, etc.), engineering (insulating materials of the new generation, self-cleaning coatings, etc.), aerospace industry (catalysts, new highly efficient fuels, resistant satellite surfaces, etc.)
Are products, produced as a result of nanotechnology processes, safe? This question is asked by modern scientists, engineers, doctors, as well as by the users of products containing nanomaterials.
Currently, it is obvious that some of the nanoparticles may be penetrated from the lungs into the blood stream and subsequently into different organs. Although it is not entirely clear what will happen if the nanoparticles enter the human body, we know for sure that the particles of "normal" size do not get into the bloodstream. The ability ofnanoparticles to enter the human body relatively easily deserves more detailed research. It is also known that some of the nanoparticles are sufficiently small to penetrate into the cells of the human body and cause their damage.
Except the possible impact on human health, nanomaterials pose a potential threat to the environment. For example, the use of silver nanoparticles as an antimicrobial agent can damage the useful bacteria in the biosphere and thus affect organisms of higher levels.
At present it is clear that the information on nanomaterials and nanoproducts is very limited. Therefore, it is necessary to be very cautious while developing, manufacturing, selling and consuming nanoproducts. It is important to develop a strategy and system of control of nanosystems, nanomaterials and products containing nanoparticles, in order to identify and describe possible negative impacts on human health and the environment.
- During my last hockey training I bumped into another player. What a clash it was! I had a black eye for a week, it disappeared just a couple of days ago.
This was the reaction of a young hockey player Zdenek to the results of his Bio-Well scanns. I measured his energy at the national-wide exhibition of innovative technologies, which was held in the Czech Republic.
For some reason Zdenek looked really amazed when he heard this comment of mine. I asked him why he was so surprised, and he explained that not a long time ago he suddenly fainted during the night. When he regained consciousness, he was surprised, but as he did not suffer from any particular diseases, he didn't even try to figure out the reason of this unpleasant occasion and just forgot about it.
Young people usually do not visit doctors very often and are not very concerned about their own health, as they cannot even assume that they might have any problems. But such cases prove that they should be concerned.
