Chinese Academy of Sciences: Improper use of nanotechnology may be compromised

if human beingsanduse of nanotechnology, they may be exposed to nano-metersOn the one hand, humans should avoid the side effects of nano-research, on the other hand, to remove the nano-pollution already in the environmentAt the 3rd Shanghai International Nanotechnology Cooperation Symposium, held in Shanghai,, a member of the Chinese Academy of Sciences, and a researcher at the Institute of Physics of the Chinese Academy of Sciences,, put forward the above-mentioned views on the safety of nanotechnologyIn the production process of nano-products, the pollution,nano-product technology but the,of nano-products, such as lack of understanding of human factors will bring harm to human beingsBut it cannot be said that the harm of nano to human beings is caused by the research and development of nano-technologyIn fact, before they were engaged in nano-research, humans were already exposed to nano-scale hazardsThe depth of thought is an example of a sandstorm: the particle size in a sandstorm is different, and it contains nanoparticlesNanoparticles are relatively easy to enter the human body, although its amount is relatively small, but the harm to people can not be ignoredFor example, the metal particles in car exhaust contain harmful organic matter, some of which is nanoIn addition, welders are affected by metal vapor, which also contains nanometallic particlesNano-pollution of the environment, in the nature of,in the human production process has long existed,is not all thefrom nano-research,can not say that nano-research opened the "Pandora's box." On the contrary
to recognize nano
andand eliminate the harmfulof nano.
'On the one hand, we need to avoid the side effects of nano-research, and on the other hand, we need to remove the nano-pollution that is already in the human environment, ' he saidHe said the Chinese government has expressed international overcharacterity and commitment to high-tech risks, including nanotechnology He stressed that if we are to test nanodrugs in humans, such as those on the delivery of nanoparticles, we must make biosafety assessments that cannot be approved without such assessments and, in short, to ensure people-centred development of nanotechnology
