Abstract
The paper presents the results of a study of the effect of carbon dots synthesized by the hydrothermal method on the strength of hydrogen bonds in water. For the first time, using Raman spectroscopy and genetic algorithms, the values of the change of the enthalpy of hydrogen bonds were obtained when carbon dots were suspended in water. According to the calculations, the energy of hydrogen bonds in water is equal to 15.5±0.2 kJ/mol, and in an aqueous suspension of carbon dots, it is 14.8±0.2 kJ/mol. The results obtained make it possible to assess the safety of the studied carbon dots as biomedical nanoagents from the point of view of the effect on hydrogen bonds in biological tissue.
