Risks of Nanotechnology


Nowadays, nanotechnology has been applied to consumer products, i.e. T-shirt with Nanosilver or Cosmetics doped with Nanoparticles. One popular question is that “Nanotechnology used has any potential risk to envelopment or to human health or not?”. Prof. Robert Schiestl from UCLA's Jonsson Comprehensive Cancer Center reported that titanium dioxide (TiO2) nanoparticles, found in everything from cosmetics and sunscreen to paint and vitamins, caused systemic genetic damage in mice. (TiO2) nanoparticles can accumulate in different organs because the body has no way to eliminate them. And because they are so small, they can go everywhere in the body, even through cells, and may interfere with sub-cellular mechanisms. In his study, mice were exposed to the TiO2 nanoparticles in their drinking water and began showing genetic damage on the fifth day. The human equivalent is about 1.6 years of exposure to the nanoparticles in a manufacturing environment......

Dear Chatchawal

I appreciate your post, It is very interesting information. I am one of the researchers that are interested in this topics.
We have to be very careful in the use of nanoparticles and nanomaterials. Due the irresponsability of many companies, the Carbon nanotubes and Silver nanoparticles can be declarated as pesticides.

Welcome

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!
