“…The presence of hydrophilic and hydrophobic DNDs in water weakens the hydrogen bonds [6,7]. With the addition of NaC8, the aggregation of DND-COOH (see results of DLS), or the decrease of the DND-COOH total surface, takes place.…”

“…It is known that in suspensions, surfactants [5], as well as NDs [3,6,7], substantially change the structure of solvent and, primarily, the strength of hydrogen bonds. The authors [6,7] showed that in aqueous suspensions the detonation nanodiamonds (DNDs) weaken the hydrogen bonds in bulk water and such changes depend on the type of ND's surface groups.…”

In this study, with the use of laser Raman spectroscopy the significant difference in intermolecular interactions of detonation nanodiamonds with hydrophilic and hydrophobic surface groups in aqueous solution of surfactants was observed. It was found that at low concentrations of sodium octanoate (before the micelle formation) the weakening of hydrogen bonds by nanodiamonds has a different dynamics for hydrophobic and hydrophilic nanodiamonds. However, with the addition of surfactants, this effect gradually decreases for both types of nanodiamonds and ends after the formation of micelles. Such effects are explained by the "shielding" effect of surfactant molecules surrounding nanodiamond particles.

“…The synthesis of the samples is described in [5,6]. We note here that 10 nm DNDs and 5 nm DNDs were treated differently, as the results of which DNDs 5 nm were obtained with much more intense fluorescence (FL) due to production of tiny carbon dots on the DNDs surface [7].…”

In this study, the interaction between DNA and the surface of detonation nanodiamonds and nanodiamonds with NV centers is investigated, and the quantitative parameters of this interaction are calculated. The influence of interaction of DNA with nanodiamonds on the fluorescent properties of nanodiamonds is established. A correlation was found between the efficiency of DNA interaction with the surface of the detonation nanodiamonds and the changes of their fluorescence: the more DNA bonds with the nanodiamond surface groups -the stronger the fluorescence of detonation nanodiamonds increases in water.

As a result of an experimental study of the Raman scattering valence bands of water in aqueous suspensions of detonation nanodiamonds with different functional surface groups, the energies of hydrogen bonds in suspensions of nanoparticles were calculated for the first time. It is shown that the degree of influence of different functional surface groups of nanodiamonds on hydrogen bonds in aqueous suspension decreases in the series H > polyfunctional surface > OH > COOH. The obtained data are confirmed by modeling of optimized nanodiamond structures in water clusters and theoretical calculations of the bond parameters in these structures by the density functional theory.KEYWORDS hydrogen bonds, nanodiamonds aqueous suspension, Raman valence band
