Visible-Light-Driven Photocatalytic Reduction Method to Fabricate... 

Well now, the proposed co-reprecipitation method [45] and visible-light-driven photocatalytic reduction method [53] have been established for the purpose of these kinds of core/shell type hybridized NCs composed of PDA NC and noble metal NP, and both processes have been further improved to extend to another type hybridized NCs, respectively [50, 54], Typical core/shell type hybridized NPs were first reported by Halas and Caruso research groups [70, 71, 73, 84, 87]. A great number of fine gold (Au) NPs as Au shell were deposited densely on the surface of silica NPs, which are spherical and uniform size. The LSP speetra were continuously blue-shifted with increasing the thickness of Au shell, and some optoelectronic applications have been now presented such as a substrate for surface enhanced Raman spectrum (SERS) measurement, chemical- and bio-sensors, etc. Silica NPs, however, are core as a template to fabricate core/sheU type hybridized nanostructure, and there is no something like optoelectronic interaction through core/shell hetero nano-interface in this case. 

This polymer-core/metal-shell type of the hybridized NCs has an inverse nanostructure of Sect. 3. Our research group has recently estabUshed the unique fabrication process, visible-light-driven photocatalytic reduction method [53], to PDA-core/metal-shell hybridized NCs.
