“…The changes in resistance observed upon Li insertion and removal can be explained by charge transfer between Li and C, analogous to that in graphite intercalation compounds. Charge transfer was previously reported in SWNT doped with various electron donors and acceptors, 32 explaining the variations in conductivity upon doping. In situ Raman measurements during electrochemical doping in LiAsF 6 EC:DMC identified a charge transfer at potentials above that of SEI formation, after which the signal was attenuated and lost.…”

In this Account we highlight the experimental evidence in favor of our view that carbon nanotubes should be considered as a new macromolecular form of carbon with unique properties and with great potential for practical applications. We show that carbon nanotubes may take on properties that are normally associated with molecular species, such as solubility in organic solvents, solutionbased chemical transformations, chromatography, and spectroscopy. It is already clear that the nascent field of nanotube chemistry will rival that of the fullerenes.

“…Resonance Raman spectroscopy has been a major tool for (n, m) characterization of SWNTs, [50,71,72] as well as the degree of p-and n-doping [73] and side-wall defects. [74,75] Laser polarization angle-dependent Raman intensity profiling is particularly suited to determine CNT orientation with respect to underlying substrates or nanotube-containing matrices.…”

The unique electronic and optical properties of carbon nanotubes, in conjunction with their size and mechanically robust nature, make these nanomaterials crucial to the development of next-generation biosensing platforms. In this Review, we present recent innovations in carbon nanotube-assisted biosensing technologies, such as DNA-hybridization, protein-binding, antibody-antigen and aptamers. Following a brief introduction on the diameter-and chirality-derived electronic characteristics of single-walled carbon nanotubes, the discussion is focused on the two major schemes for electronic biodetection, namely biotransistor-and electrochemistry-based sensors. Key fabrication methodologies are contrasted in light of device operation and performance, along with strategies for amplifying the signal while minimizing nonspecific binding. This Review is concluded with a perspective on future optimization based on array integration as well as exercising a better control in nanotube structure and biomolecular integration.
