TUBALL single wall carbon nanotubes: No ecotoxicity found, unlike other carbon nanotubes

Testing of the ecotoxicity potential of TUBALL single wall carbon nanotubes, carried out according to the relevant OECD guideline, has shown no toxic effects on algae, in contrast to a set of recent results on similar tests with multi wall carbon nanotubes. Among plausible reasons for this is the unique physical nature, particularly the high flexibility, of single wall carbon nanotubes compared with most other types of carbon nanomaterials.
