Abstract
The present invention relates to labelled silica-based nanoparticles with enhanced properties, to process for preparing them and to uses thereof.
Claims19
A nanoparticle comprising:
- a nonporous silica core, having a diameter of about 1 nanometer to about 200 nanometers, and comprising a first organic label bound to the silica core, wherein the first organic label is a first fluorescent dye or a first phosphorescent dye;
- a silica shell surrounding the silica core, the silica shell comprising a second organic label distinct from the first organic label;
- and
- a layer of polyethylene glycol molecules covalently bound to the silica shell.
