  We have fabricated layered nanocomposite consisting of a nanoporous anodic
alumina sublayer (AOA), an ultrathin metal-containing polymer Langmuir-Blodgett
(LB) film coating AOA, and multi-walled carbon nanotube (MCNT) - bundles which
are arranged on the LB-film. MCNTs were preliminarily chemically modified by
carboxyl groups and functionalized by stearic acid. We have experimentally
observed an enhancement of Raman light scattering on surface plasmons in the
LB-monolayers. This enhancement is due to charge and energy transfer. We
demonstrate that propidium iodide (PI) fluorescence is quenched by the
MCNT-bundles. A method of two-dimensional system imaging based on the
MCNT-enhanced Raman spectroscopy has been proposed. This method has been
applied to visualize focal adhesion sites on membranes of living PI-labeled rat
glioma cells.
