Carbon nanotubes (CNTs) are considered one of the most popular types of nanomaterials and in the last few years have gained tremendous interest in a wide range of applications due to their unique physical, chemical, and electronic properties. Multi-walled carbon nanotubes (MWNTs) consist of sheets of carbon atoms rolled up into multiple concentric hollow tubular structures.[1] The lack of dispersibility of pristine MWNTs in most solvents is owing to strong inter-tube van der Waals forces and this has been an obstacle for their effective use in biological applications and material sciences (i.e. composites).[2,3] This may be largely overcome by surface modification of the nanotube backbone, allowing application of CNTs in biomedical applications.
