Development of Organic‐Dye‐Doped Silica Nanoparticles in a Reverse Microemulsion

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.
