Краткое описание
The development of the physicochemical basis for applications of nanoradiosensitizers for targeted treatment of tumors is one of the crucial issues of modern radiotherapy. Ceramic nanoparticles (NPs) composed of heavy metal oxides are considered as prospective sensitizers, particularly for X-ray treatment. This study reports a novel approach for experimental simulations of the radiosensitizing effect of NPs in biomimetic systems based on the quantification of radicals produced from organic components in concentrated aqueous organic solutions using the spin-trapping technique with electron paramagnetic resonance detection. This approach was first applied to X-ray irradiation (45 kVp) of aqueous methanol solutions systems containing different concentrations of hafnium oxide nanoparticles with an average diameter of ca. 84 nm (up to 1.8 wp). It was found that the amount of radicals produced from methanol at the same exposition time increased linearly with the increasing content of HfO2 NPs. The effect can be...
