Carbon nanotube SWNT hybrids

The use of electrodes modified with immobilized redox-active molecules provides a simple methodology by which to study the ultrathin film electrochemistry of water-insoluble redox-active molecules, encouraging the application of such techniques to biomimetic membranes in aqueous media. It is of interest to use monolayer and LB films of enzymes, proteins, and antibodies as biosensors or biomolecular switches because of their high sensitivity for their substrates and antigens, respectively. The formation of thin fullerene films including fullerene-lipid hybrid and fullerene-lipid composite bilayer membranes is of interest both from a fundamental and practical application point of view. Multiwalled carbon nanotubes (MWNTs) and single-walled carbon nanotubes (SWNTs) are novel nanomaterials that have remarkable electronic, mechanical, and thermal properties, and specific functions. Soluble carbon nanotubes in aqueous and organic systems are of interest since their study allows the...

Similarly P-P, meso-meso, P-P triply linked dimers were obtained by Diederich and CO workers. They showed that such dimers led to weU-organized self-assembled networks on silver surfaces [162, 163]. Similar self-organized networks were observed for hybrid Ceo-triply linked dimer assemblies [162, 163]. Hybrid assemblies between single-walled carbon nanotubes (SWNTs) and triply linked trimers were also investigated and allowed the formation of stable supramolecular carbon nanotubes-porphyrin complexes [164]. 

In another example [56] SWNT was modified with peroxytrifluoroacetic add (PTFAA). Raman spectrum of the carbon nanotubes after the FIFA A treatment shows a D-line substantially increased indicating the formation of defect sites with sp3-hybridized carbon atoms on the sidewalls due to the addition of the functional groups. The RBM bands in the region of 170-270cm-1 decreased and shifted to higher... 

Carbon nanotubes are shells of sp -hybridized carbon atoms that form a hexagonal network within a tubular motif closed at the ends by hemispherical endcaps. Manufactured as single-walled (SWNTs) or multi-walled (MWNTs) systems with different diameters and lengths, each type of CN has different properties.
