| abstract |
The invention relates to a novel use of ultrafine nanoparticles, which are of use as a diagnostic, therapeutic or theranostic agent, characterized by the mode of administration thereof via the airways. The invention is also directed towards the uses which follow from this new mode of administration, in particular for imaging the lungs, and the diagnosis or prognosis of lung diseases. In the therapeutic field, the uses envisaged are those of radiosensitizing or radioactive agents for radiotherapy (and optionally curietherapy), for neutron therapy, and of agents for PDT (photodynamic therapy), in particular for treating lung tumours. |
