Since we first wrote this monograph in 2005, the science of nanotubes and
nanowires has had an explosive growth. Carbon nanotubes have attracted
the attention of chemists, physicists, materials scientists and biologists
because of the various fascinating properties that they exhibit. Raman spectroscopy
and other techniques have been effectively employed to understand
the structure and properties of nanotubes. Functionalization and solubilization
of carbon nanotubes have been explored widely. Aspects related to
potential applications of nanotubes have been widely investigated and they
include not only electronics and sensor technology, but also nanobiotechnology
and catalysis. In this revised edition, we have covered the varied developments
in carbon nanotubes up to 2010 citing over 2000 references.
