In this work we prepared colloidal CdSe-CdS core-shell nanocrystal emitting @625 nm and, by a micro-emulsion procedure of water in oil inverse micelle, we encapsulated a single dot inside each silica sphere. In this way the nanoparticles became biocompatible, are simply to prepare and could be used also in a water based environment. Moreover, the silica shield is transparent to the wavelengths of interest.
