Nanotechnology: The tiny unknown
Nanotechologien are already widely used. The particles enter through air, skin, water and food into the body. What the tiny par sony pcga-ac19v3.
Nano is the most revolutionary cry which has produced the technology in recent years. But before explaining how the small particles that are used in the various technologies used, have an impact on health, they have already found entry into everyday life. Very critical is the national institution and therefore has published a guide booklet, which grapples with the world of Tiny.
From Nano is spoken, if used materials are made of particles in the order of one to about 100 nanometers. Nanotechnologies are not uniform and therefore difficult to evaluate in general. They are used for example in computer technology, as tiny electronic component Chen, in coatings thinkpad x60 battery, such as automobile paints or sanitary facilities, but also in textiles, cosmetics and in foods and in products for children, such as pacifiers or toys.
The development has raised great hopes in medicine. The aim is among other nanoparticles act as an intelligent drugs and ferries to transport drugs directly into cancer or tumor tissue. has the side effects, today's drugs on the healthy tissue would disappear with it, hope.
But the problem is, the consumer advice that some substances in crude form, although harmless, subtle brought to the nanoscale, but this will be the violent reactions to light can. One reason is the enormous increase in surface area. But even the smallest particles out into the body slightly in cells or even enter the nucleus and changes cause confusion or cause cell processes.
Other reaction in nano-sized
Example, it is proven that although titanium dioxide in Grobform causes no damage. But nano-sized effect of a substance that is also often used in cosmetics, such as suntan lotions, toxic and could reach about small scratches in the skin into the body. There it can be liver, kidney and heart muscle damage and result in the destruction of genetic material in cells. Whether titanium dioxide but in a product or tiny rough occurs to the contents list is not visible. After all, the use of nanoparticles is not yet classified.
A grievance, which urgently needs to change, the Consumer calls in its brochure. "The existing laws should be adapted to nanomaterials as new substances, without exception, must" be treated and admitted, it said. Also had a lot more money flowing into risk research. Currently, the federal government promotes nanotechnology pcga-bp2nx battery with around 370 million € per year. Only a fraction was used for the study of impact on environment and health. This percentage should be increased to at least ten to 15 percent. To clarify the risk, children should receive special protection and nanotechnology to develop products subject to stringent limits for children.
Nanoparticles something from the clothing or washing machine technologies can, despite a relatively close relationship gets accidentally into the body where they detach from the material and be inhaled or landing in the water during the washing cycle. This concerns about nano-silver, the antibacterial effect, or the Nano-Tex technology, as used in jackets around the brand Jack Wolfskin and identified. There was also no adequate studies Nano-Tex, the dangers and risks to exclude conclusively how Jack Wolfskin communicates itself. Previous tests, however, would suggest that the technology is safe, the company said.
Risks and dangers, very little research
It had already been established that Nanosilberpartikel in the body can cause a damage to the liver and brain cells, says Professor Richard Raedsch the professional association of internal medicine. Most applications of nanotechnology and its impact on the environment and health are still studied.
In the food industry, nanoparticles can be used, for example, as flow aids for dried soups or spice mixtures and to prevent optical changes in chocolate. Of great importance is the addition of nanoparticles to stabilize them in both the product itself and in the packaging.
"Currently, there is for the consumer is not possible to detect whether nanomaterials in the manufacture of a product were used. However: The less a food has been processed industrially, the less likely it is that it was mixed with nanoparticles, "advises Raedsch. Only a few products are actually a nano-mark.
Further details for the use of nanotechnology are "additives such as textiles, household pcga-bp2ny battery appliances and products for children such as" antibacterial "or" germ-free, advises the Consumer. Also, there is now a nano product directory of the Woodrow Wilson Center. But that is far from complete and only available in English.
