Polyelectrolyte layers uniform nanoparticle deposition

To make the containers sensitive to IR laser light, preformed silver nanoparticles were directly incorporated into the polyelectrolyte shell. For this purpose, AgNPs were added into solutions of polyelectrolytes for LbL deposition and hence fixed between the polyelectrolyte layers. The AFM images of the resultant nanocontainer-impregnated him showed a uniform distribution of the containers over the coating, with the concentration of the silica containers equalling 107 containers per meter squared.
