Fluorescent nanoparticles

摘要

Use of fluorescent nano-particles comprising an inorganic core, a passivation layer and specific ligands, for the production of in vivodiagnostics, where the nano-particles exhibit an emission spectrum700 nm and hydrodynamic diameter of the inorganic core with the passivation layer is15 nm, preferably 5 nm. Independent claims are included for: (1) nanoparticle exhibiting an emission spectrum of 600-700, preferably 620-650 nm; and (2) a pharmaceutical composition comprising the nanoparticle.
