Аннотация:In this work, boron-doped nanodiamonds of various sizes were approbated as an agent for local hyperthermia of the cell medium — chicken protein. Based on the heating data and the results of the absorption spectroscopy, the dependencies of the heating ability of boron-doped nanodiamonds on their size and wavelength and power of laser radiation was shown. Approbation results confirm that boron nanodiamonds are promising agents for local hyperthermia.
