Nanoparticle technology and malignant tumors

I do not know whether or not you know that nano-particles in the atmosphere is toxic, and people walking on the street per hour through the air into the lungs of nano-particles of about 100,000,000. However, there are two sides to anything, if the use of nanotechnology in biological medicine, clothing, household goods, it emerged on the merits of it. A human lung inhalation of nanoparticles per hour, about 100,000,000 "nano-particles in the atmosphere caused by the poison developed in the early used to be a serious problem in Europe and the United States, the epidemic survey found that nano-particles in urban air and the incidence of urban population, especially Cardiovascular disease morbidity and mortality close. "Institute of Biophysics, Chinese Academy of Sciences researcher Zhao Paul introduced. He said that the nanoparticles into the respiratory tract, the first precipitation in the upper respiratory tract, 80% of the particles in the nasal cavity, Shen, the other in the bronchial precipitation, and also a number of Shenyang in the alveoli, when more than deposition to a certain extent, this will affect the Normal lung function. "Estimate, walking in the streets of pedestrians per hour through the air into the lungs of the nanoparticles are about 100,000,000." Zhao Paul introduced. B nanotechnology is not a panacea for the country to see how the use of nano-science and nano-bio-medical centers and nano-safety researcher at the Laboratory Xing Jie accept Chinese Commercial News reporters Cai Fang and Shi Yue, in addition to using nanotechnology in medicine, we usually hear of nanotechnology Or see the nano-refrigerators, clothing and so on nanotechnology is the use of nanotechnology, or nano-assisted technologies create, does not mean they are done with nanomaterials, we should not be exaggerated the number of manufacturers and misleading propaganda. "Some of the refrigerator is the use of nano-technology manufacturing, generally refers to the internal refrigerator plus a layer of nano-silver, disinfection of effect; if nanomaterials used in clothing, can change the fabric of tough, flexible, nano-technology The use of well deodorant can be made socks. "Jie Liang said.
