Disclosed is the use of fluorescent nanoparticles containing an inorganic core, a passivation layer, and specific ligands, the inorganic core with the passivation layer having a maximum hydrodynamic diameter of 15 nm, preferably 10 nm, most preferably 5 nm, for producing an in vivo diagnostic agent. The inventive nanoparticles are provided with an emission of less than 700 nm. |
