ULTRAFINE NANOPARTICLES AS AN IMAGING AGENT FOR DIAGNOSING A RENAL DISORDER

The invention relates to a novel use of ultrafine nanoparticles as an imaging agent in a method for diagnosing a renal disorder. The invention also relates to the use of ultrafine nanoparticles as an imaging agent in methods for monitoring the therapeutic effectiveness of a renal disorder treatment. Said nanoparticles include: (i) a polyorganosiloxane matrix (POS); (ii) one or more chelating agents grafted onto the POS matrix by -Si-C- covalent bonding; and (iii) one or more metal ions chelated by one or more of the aforementioned chelating agents.
