As a result, numerous safety assess

As a result, numerous safety assessments have since been conducted internationally.4 Safety concerns have been placed on some of the thickest and longest MWCNTs in recent years;5,6 however, MWCNTs have been increasingly reported as safe biomaterials, provided that the extent of inhalation exposure does not reach critical levels

其結果是，大量的安全評估，至今已internationally.4的安全問題進行了一直放在一些最厚和最長的碳納米管近年來，5,6然而，碳納米管已經越來越多地報告為安全的生物材料，只要程度吸入暴露沒有達到臨界水平
