One-dimensional copper nanoparticles have been easily organized by
one-step wet chemical technique. Dicarboxylic peptide bolaamphiphile
coordinated with copper ions to form metal-lipid hybrid nanofibers
in water. When copper ions were reduced by hydrazine using hybrid
nanofiber as a template, a gray colloidal dispersion was obtained.
TEM of the colloidal dispersion show the existence of fibrous assemblies
and large aggregates. High-magnification TEM also clarified that nanoparticles
with diameters of 1-3nm are organized one-dimensionally at intervals
of 2-5nm.
