Project Summary:

The project Controlling FRET by surface plasmon resonance in multiplayer „core-shell” metallic nanoparticles towards efficient nanoscopic light sources, proposes to develop a novel strategy for designing a model of multilayer core-shell AuNPs with optimized photophysical properties, consisting of a Au core (i.e. spherical and rod-like shape) and surrounding FRET  pairs (i.e. fluorescent molecules and quantum dots). We will employ polyelectrolyte multilayers fabricated using layer-by-layer assembly as dielectric spacers for precisely tuning the Au core/acceptor/donor distances and to modulate FRET enhancement. We consider that our project represents a real challenge with promising results considering that the integration of NPs with fluorescent molecules into composite nanostructures where the emitters are precisely positioned relative to the NPs surface enables the use of these multilayer core-shell AuNPs as ideal efficient nanoscopic light sources.
