Nanomaterials and their impact on human health have long been a topic, both among the lay world and in the scientific community. Scientists point out that nanomaterials have flooded people's everyday life, but the dangers they pose to human health are still unknown.
Present in cosmetics, textiles, concrete and car manufacturing, nanometric substances (billionths of a meter in size) have different effects, depending on their size.
Various studies conducted on animals have shown that depending on inhaled and eaten nano particles, certain disorders occur in living organisms. First of all, to the appearance of lung infections, heart rhythm disorders, the formation of blood clots, but also diseases of the brain, liver, spleen and spinal cord.
Nanomaterials, as experts warn, are being produced more and more, and therefore are being used more and more. In this way, people are increasingly exposed to the negative effects of their use.
Scientists also point out that not all diseases caused by nanoparticles are known yet, that knowledge is patchy, and that the danger is still a concern.
The number of companies using nano technologies is increasing, which greatly complicates the registration of places exposed to these particles.
Nanotechnologies are everywhere, both in places of residence and the environment, as well as in the fields of energy, healthcare and the automotive industry. This, as the scientists point out, is the result of striving for higher performance of certain products.
Nanotechnology has the potential to make revolutionary advances in all areas of life. However, potential health risks from industrial nanoparticles, possible abuses in the application of nanomaterials to human biology and the environment are still under great question. Manipulation of matter at the atomic and molecular level also affects DNA, and the consequences of this are still not clearly discernible. It opens up very serious topics, which require much more exact answers and appropriate laws and regulations - precisely because of possible very serious abuses.
The use of nanotechnology in medicine
The use of nanotechnology in medicine ( nanomedicine ) will become commonplace in the near future. Currently, many substances are being studied in detail to investigate their characteristics in drug delivery to the target site. It is interesting that experts in the field of pharmaceutical sciences use nanoparticles to reduce the toxicity and numerous side effects of drugs. However, they did not realize until recently that the carrier formulations themselves may carry certain risks for the patient. This is a limitation in their application.
The benefits and dangers of nanoparticles for human health are still not fully known, so extreme caution is necessary in their daily use. One of the recent sensational discoveries is related to nanoparticles designed to kill cancer cells. This discovery is extremely important, because it could prevent a large part of mortality caused by cancer.
