Nanoscale, 2011, DOI: 10.1039/C0NR00779J


In this study, the authors compare the biodegradation of SWCNTs and MWCNTs using two different oxidative conditions. They demostrate  that treating oxidized multi-walled carbon nanotubes with horseradish peroxidase in the presence of hydrogen peroxide, degrades the MWCNT almost to completeness.

With an increasing industrial production and presence of CNTs, the exploration of their biodegradation is of fundamental importance, especially for biomedical applications.
