We synthesized statistical poly(2-isopropyl-2-oxazoline– co –2-butyl-2-oxazolines) (POXs) that are molecularly dissolved below their cloud point temperature in aqueous milieu and are incorporated into micellar nanoparticles of biocompatible Pluronic F127 (F127) after heating their solution above transition temperature, T tr . A functional comonomer 2-(but-3-enyl)-2-oxazoline copolymerized into one of the POXs (polymer E) allows introduction of fenolic moieties and subsequent radionuclide labeling with iodine-125. Self-assembly of the polymer E with F127 leads to formation of radioactive nanoparticles with hydrodynamic diameter 20 nm in aqueous solution by heating to 37° C. The nanoparticles are intended to be used as radioimaging tool in solid tumor diagnostics.
