Indiumilica core-shell nanoparticles as plasmonic enhancers of molecular luminescence in the UV region

Large fluorescence enhancement of UV-active molecular models Carbostyril 124 and tryptophan by core-shell indium-based plasmonic architectures demonstrates the metal's potential in the design of bioprobes. Precise control over the metal-fluorophore distance is achieved through the controlled deposition of a uniform silica layer over the nanosized indium particles.
