Synthesis of hybrid multicomponent disklike nanoparticles

This manuscript describes the synthesis of a new generation of multicomponent disklike nanoparticles. In this work, we present for the first time, through the template-based sequential electrochemical deposition of metal/semiconductor/polymer segments, an innovative and effective method for preparing a wide range of metallic, semiconductor, and polymeric hybrid multicomponent disklike nanoparticles covering a wide and controlled dimension range from a few nanometers to hundreds of nanometers. Moreover, we can readily tailor the desired final size, aspect ratio, and composition of the disklike nanoparticles by varying the precursor material used and the electrochemical deposition approach. Furthermore, this simple route leads to a highly reproducible and high-throughput synthetic platform of new multicomponent and multifunctional nanoscale building blocks. © 2008 American Chemical Society.
