Abstract (en)
[origin: WO2021014103A1] The present invention concerns a particulate structure characterised in that it comprises: a/ a biodegradable polymer particle, b/ gold nanoparticles covered on their surface with macrocyclic chelators complexing at least one ion of interest and/or a radionucleide for medical imaging, c/ a polycation having a positive charge over a pH range from 5 to 11, the gold nanoparticles b/ being encapsulated in the polymer particle a/ and/or adsorbed at the surface of the polymer particle a/. The invention also relates to a method for preparing the particulate structures. The invention further concerns the use of the particulate structures for radiotherapy or chemotherapy in the context of cancer treatment.
