Stained with " nanometer " Is it good? The academician reminds and watches out for its toxicity
News of Jingchu net (the newspaper of city of sky above Hubei and Hunan) (the intersection of reporter and competence Lu) The day before yesterday, Yao ShouZhuo, academician of Chinese Academy of Sciences, proposed while participating in a seminar in Wuhan, watch out for the nanometer material to the toxic function of human body and environment, and propose studying toxic systematicness about nanometer at home as soon as possible.The same day, the chemical science department " 12 five " in National Natural Science Foundation of China The discipline development strategy seminar of analytical chemistry is held in Wuhan, nearly one hundred scientists discuss " 12 five " together Research main direction of analytical chemistry during this time.
Among the meeting, academician Yao ShouZhuo has issued the above-mentioned suggestion.According to the introduction of honest and poor academician Yao, the nanometer material has caused the scientists' extensive interest since the 1990s of last century, enter the 21st century and get unprecedented swift and violent development especially, its application has already been expanded to each field including disciplines such as chemistry, material, physics, living beings, environment, medicine,etc. at full speed. But the research about the toxicologic respect is far from keeping up with the speed of material one's own application development of nanometer. It is also at the stage of a dispute to the human body, influence on emerging in environment,etc. too now, it is assessed let alone quantitative. Even also there is a kind of thinking now, think " only involved in nanometer, it is all good " . So, develop new analytical technology and specially analyze that distinguishes some potential danger in application of such new material to the toxicity of the nanometer material, it is a task that should be finished first to use and popularize it correctly.It is introduced, have already begun the research in this respect in the world.ChainingNanometer: Nanometer (nm) It is the long measure, called millimicron originally, it is equivalent to 1/1 billion meters, atom size of 4 times.The so-called nanotechnology, mean in 0.1~100 nanometers of yardstick, the movement law in research electron, atom and molecule and a new technology of the characteristic. The scientists find several, dozens of denumerable atoms or molecules isolated out under nanometer yardstick while the material forms to study, demonstrate a lot of new characteristics prominently, and make the technology with particular function apparatus with these characteristics, called nanotechnology.
