Fullerenols interact effectively with radionuclides and their degradation products due to their water solubility and antiradical activity. By protecting cells from damage, they “take the brunt” of radiation, said Nadezhda Kudryasheva, a professor in SFU’s Department of Biophysics. In his opinion, this makes fullerenols promising radioprotectants.
For the experiments, scientists used the bacterium Photobacterium phophorum, whose brightness increases under the influence of tritium. The addition of fullerenols reduced the luminescence level to control values without affecting the overall metabolism of the bacteria. There was also a decrease in the amount of reactive oxygen species that destroy cells.
