Abstract

Carbon nanotubes (CNTs) have been advocated as promising candidates in a wide variety of fields due to their excellent physico-chemical properties. The potential of carbon nanotubes can be further expanded via their modification with inorganic materials, forming carbon nanotube-inorganic hybrids. For instance, the inner cavity of CNTs can be filled with a chosen payload whilst the outer surface can be modified to improve their processability. Following this approach, we achieved ultra-sensitive imaging by encapsulation of radioactive metal iodide, of interest in the biomedical field. Further studies in our labs on the encapsulation of metal halides into the cavities of CNTs have lead to the observation of rolled up 2D-single-layered crystals. Such materials combine the properties of both 1D and 2D systems. Decoration of the external surface with inorganic nanoparticles also results in the formation of novel systems with advanced properties. We have recently developed CNTs for dual imaging by radio-labelling iron oxide decorated CNTs. The resulting hybrids allow magnetic resonance (MR) and single photon emission computed tomography (SPECT) imaging
