Nanometer may damage the brain cell to oxidize titanium two times
Scientist of U.S. Environmental Protection Agency discover particle extremely very small nanometer two oxidize the intersection of titanium and particle, may make in the brain cell producing harmful free radicalling. This means people must further investigate the influence on organizing in biology of nanometer material, assess it to environment and healthy threat. Nanometer oxidizes titanium and antibacterial, only catalyzes, resists ultraviolet ray,etc. characteristic two times, used for many kinds of products such as antibacterial material of manufacture and sun-proof cosmetics,etc. extensively, but it have any influence on biological organization, people still knew little about before the this. Have, discover some have toxic material when being processed into the ultra microparticle of nanometer range actually once, will become harmful. These materials will impel the living beings to produce and contain the biological molecule of activity of oxygen while organizing, such as free radical. Because some nanometers of particles will reach the brain after entering the blood system, the researchers of the U.S. Environmental Protection Agency decide to observe and oxidize the impact on little mouse brain cell of titanium two times. According to the 15th of American Science website, researchers soak the small colloid cells of the little mouse brain in containing solution that micro- nanometer oxidizes the titanium two times, small colloid cells protect brain against the virus or cells that the outside chemical material encroached on. The experiment finds, small colloid cells have absorbed and oxidized the titanium particle two times, and release and include oxygen active molecule in two hours continuously. These molecules have not damaged small colloid cells, but contacting this kind of molecule for a long time will make the nerve damage. The expert thinks, though affirm it is much too early for nanometer to oxidize titanium and harmful to health two times in view of the above, but this result reminds people to be be serious about the health damage that the nanometer material may bring, carry on more research and strick precautions.
