Description
Summary:This study describes the preparation and characterization of novel multilayer core−shell nanoparticles displaying metal-enhanced Förster resonant energy transfer. The increase in range and efficiency of Förster resonant energy transfer in these fluorescent nanocomposites and their vastly improved luminosity make them promising optical probes for a variety of applications such as cell imaging and biosensing.
