Progress on Cytotoxicity in Vitro of Carbon Nanotubes

摘要

According to recent references, the progress on cytotoxicity in vitro of carbon nanotubes (CNTs) including the factors such as size, residual metal catalysts, and detection methods influencing cytotoxicity of CNTs are summarized. The results shown that residual metal catalysts must be removed as much as possible and ensure CNTs in some concentration range before using them. Biocompatibility of CNTs must be considered and chemical modification of CNTs to improve their use safety and advantages is indispensable.
