- We report a feasible fabrication of binary complex particles based on polyelectrolyte multilayer-coated particles (PEMPs). Binary complex
particles were synthesized by combination of large organic and small inorganic nanoparticles. The PEMPs were prepared by alternating
adsorption of two kinds of polyelectrolytes with opposite charges onto colloidal particles. In this structure, polyelectrolytes act as a matrix to bind
precursor for metal nanoparticles. Following reduction and hydrolysis of the PEMPs could generate bimetallic complexes onto PEMPs. We found
that size and composition of the bimetallic complexes depend on the amount of gold precursor added to the suspension of the PEMPs.
