Abstract / Description:Two examples of selective electrochemical modification of
individual nanoscale objects are presented, namely the
electroless metallization of a plant virus, and the coupling of
substituted phenyl residues to single-wall carbon nanotubes
(SWCNTs). The electroless deposition of metal was achieved
selectively on the inner or outer surface of tobacco mosaic
virus (TMV) particles. Covalent modification of SWCNTs,
deposited on a Si/SiO2 substrate, was performed successfully
via reductive coupling of a 4-nitrobenzenediazonium salt in
non-aqueous medium. An organic layer with a thickness of up to
several nanometers could be deposited on isolated tubes and
thin bundles. (C) 2002 Elsevier Science B.V. All rights
