Abstract

CARS method was used to study the interactions of biomacromolecules with carbon dots synthesized by the hydrothermal method. A significant effect of CDs on molecular bonds in DNA chains during their interaction in water was found. As a result of the analysis of the obtained CARS DNA spectra before and after their interactions with nanoparticles in water, markers were identified that indicate the presence of oxidative stress on DNA strands in the presence of CDs.
