China will use nano-technology water pollution |
Nanotechnology enjoy it! At the Third Shanghai International Cooperation Seminar Nanotechnology opening in November, more than 350 representatives from the United States, Britain, Australia, France and other 15 countries, jointly issued the invitation to the public. Scientists have brought the latest progress of the study and application of nanotechnology outlook report, put forward more rational advice: Let nanotechnology to help people solve more problems, should follow the "guidelines."
Nanotechnology is not a panacea
"Nano is not a panacea." Chinese Academy of Sciences, the National Basic Research Program 973 "Performance and application of basic nanomaterials and nanostructures," chief scientist Xie Sishen, a media access linking the first sentence in the case emphasized. Nanotechnology is an integrated science and technology, including astronomy, geography, biology, physics, chemistry, and other disciplines. However, the involvement of a multidisciplinary easy to give the wrong impression - that nanotechnology can solve all problems. In fact, nanotechnology only find the entry point in case it is suitable to solve the problem it solves. We can not blindly do research using nanotechnology.
"Father of biological material" known as the American Academy of Engineering, University of Washington professor Hoffman, nano-biomedical field, everything is under strict and careful management and control. "First things not because we are nanoscale research, but because it is a drug, or come into contact with human skin into the body."
Improper use can cause harm
Xie Sishen Chinese Academy of Sciences said that if the developer or improper use of nanomaterials will cause harm. Such as the production process, inadequate protection, pollution and the environment; use, lack of knowledge or technology, however, these should be absolutely avoided. As for the "Na Mike skill manufacturing ''machine flea''" Fear and the like, it is science fiction imagination, current human science and technology is far less than this level. As a responsible country to promote and conduct research in nanotechnology, our country has supported research in nanotechnology safety of several, and the world''s advanced level synchronization.
He also stressed that the harm caused by nanomaterials may not bring nanotechnology research, but in nature and human life, and previous production already exist. For example, in particle sizes of sandstorm, it contains nano-scale, easily inhaled into the lungs. In another example, vehicle exhaust and welding metal vapor, against one of the ways the human body is one of nanoscale materials. Humans to recognize, monitor and eliminate harmful nano, nanotechnology research must be carried out in order to govern nanotechnology Nano hazards. According to Xie Sishen, China''s scientists are trying to use nanotechnology to control heavy metal contamination of soil and water in small watershed.
