Bright and Stable Core−Shell Fluorescent Silica Nanoparticles

A class of highly fluorescent and photostable core−shell nanoparticles from a modified Stöber synthesis in the size range of 20−30 nm is described. These nanoparticles are monodisperse in solution, 20 times brighter, and more photostable than their constituent fluorophore, and are amenable to specif...
