Title: Asbestos-like Pathogenicity of Long Carbon Nanotubes Alleviated by Chemical Functionalization
Date: 2/2013
  Link to Journal Abstract
Abstract: The apparent similarity between multi-walled carbon nanotubes (MWNTs) and asbestos fibers has generated serious concerns about their safety profile. The asbestos-like pathogenicity observed for long, pristine nanotubes (NTlong, see scheme) can be completely alleviated if their effective length is decreased as a result of chemical functionalization, such as with tri(ethylene glycol) (TEG).
Non-technical Summary: This study investigates the effect on asbestos-like pathogenicity for long, pristine nanotubes (NTlong) that might occur by shortening the effective length of the nanotubes as a result of chemical functionalization, such as with tri(ethylene glycol) (TEG).
