How safe are carbon nanotubes?.

摘要

Carbon nanotubes are increasingly being used in everyday products such as sporting equipment, biomedical devices and aeroplanes. But questions remain as to how safe these nanotubes really are.rnA main factor in nanotube toxicity are the metal contaminants that remain from manufacture, which are typically one to ten per cent by weight, say Martin Pumera and Yuji Miyahara at the National Institute for Materials Science, Ibaraki, Japan. 'Carbon nanotubes are often viewed as homogenous materials, which is of course incorrect -they often contain impurities which are not even listed by the manufacturers,' says Pumera.
