Naif's project: The Ecotoxicology of Carbon Nanotubes (CNTs) in Marine Sediment

Carbon nanotubes (CNTs) are cylinder-shaped macromolecules made up of one or more layers of carbon atoms. 

Due to their commercially important characteristics, CNTs have been the subject of much research since their discovery. CNTs may be categorized as single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs). CNTs have high commercial potential as a raw material for different industries, owing to their unique structure and extraordinary mechanical, thermal, optical and electrical properties. Carbon Nanotubes show a unique combination of stiffness, strength, and tenacity compared to other fibre materials which usually lack one or more of these properties. Thermal and electrical conductivity are also very high, and comparable to other conductive materials.

As a result of this widespread use of CNTs, the potential for releases in to the environment, particularly the marine environment since it is an ultimate sink for contaminants.

Initial studies will be focused on the behavior of CNTs in the marine environment. Future studies will be focused on bioavailability and Toxicity of CNTs and sediment-associated contaminants to benthic marine organisms.
