Abstract
This paper presents the results of studying the interactions of DNA chains with nanodiamonds (ND) with NV centers by CARS spectroscopy. As a result of a comparative analysis of the obtained CARS spectra of DNA in water and in aqueous suspension of ND, a sign of the destruction of DNA chains as a result of interaction with the surface of ND was found. It was confirmed that DNA molecules interact with the surface groups of nanodiamonds by means of electrostatic interactions: no new CARS spectral bands were detected in the CARS spectra of DNA in the ND suspensions.
