Abstract

A new synthesis method to produce various organic-dye-doped silica nanoparticles using a reverse microemulsion has been developed. These nanoparticles show extremely high fluorescent signals (see Figure), excellent photostability, and size uniformity and tenability. These dye-doped silica nanoparticles can be used for various applications, especially in ultra-sensitive bioanalysis and in biomedical monitoring.
