The nanometer particle may initiate the unfavorable health of cancer
Beijing, November 17 (Xinhuanet) praised as the future the nanotechnology of science and technology has already urged to grow multiple invention and creation, including face reduce wrinkle and the intersection of beer and the intersection of bottle and intensity upgrade and not anhydrous to wash etc.. But scientist say need, go on research could fully understand their impact on health for many years. Some discovers, some nanometers of particles that project science makes recently may initiate cancer.


Nanotechnology can be created and controlled 1 nanometer size material. 1 nanometer is

1 meter
1/1 billion. Compared with this, Wan's nanometer that the diameter of a stick of hair is probably 8. The scientist says, through controlling the particle of nanometer, expected the atom make the miniature machine of excess of exports one by one, seem it is the same to be fostered and born in the object from single cells.

The problem is, perhaps these particles are harmful to human body. Unless nanometer particle is getting more small very, it so can penetrate cell membrane,at the same time and so big that we are enough to bring D N A chain into foreign matter.

According to Reuter's recent report, researchers find, brain cancer on a few carbon nanometer material future trouble of fish's uptake. The experimental mouse is sucking carbon nanotube ' Tube molecule composed of carbon atoms) And then symptom of pulmonary tuberculosis appears, it seems that it is the same to suck the asbestos particle.

U.S.A. environmental protection association health problem chief scientist John and Barr and Booth says: "The idea thinking all these things harmful is groundless. But we should act prudently, because they have the ability to enter our health, reach the position where the general chemical material can't be reached. "

Because find " Carbon - 6
0 "
(the globular member composed of 60 carbon atoms) And Harry and Crow who wins 1996 Nobel chemistry Prize asks the professor to say: "We should realize, the mistake appears, dangerous will appear too. But say, nanotechnology may demonstrate extreme value from the other side. "
