Popis:	The heat release during electromagnetic high-frequency (HF) heating of solid-state nanoparticle (NP) suspensions in an electrolyte with physiological solution conductivity is studied. It is shown that heating of a colloidal NP solution in an electrolyte should be calculated taken into account the contribution of an electric double layer formed near the NP surface, and the heating efficiency is controlled by the NP conductivity and the ratio of the frequency of radio-frequency radiation and the electrolyte conductivity. The optimal conductivity of silicon-based NPs for hyperthermia is determined as a function of the HF radiation frequency.
