Our research group is working on the development of multilayer core-shell nanoparticles (NPs)
featuring a metal core surrounded by concentric silica layers containing fluorophores positioned
at precise distances from the core. Recent results show that the controlled geometry of these
core-shell NPs enhances fluorescence intensity and photostability several-fold through
plasmonic coupling with the core and improves Förster Resonant Energy Transfer (FRET)
efficiency and range between donoracceptor pairs. These enviable characteristics make such
multilayer core-shell NPs a promising alternative to improve detection sensitivity, photostability as well as FRET range and efficiency in a variety of applications.
