Due to its unique properties, nanodiamonds (ND) are believed to be very promising material for biological uses. It was shown that ND can be used as sorbents of different organic/inorganic ions, as biomarker and as drug delivery agent. The surface of nanodiamond can be purposefully modified for specific problems. In order to increase sorption properties (quantitatively and qualitatively) it is very important to understand adsorption mechanisms on the surface of ND. This work presents the results of a study and analysis of mechanisms of biomacromolecules adsorption on the surface of original and modified ND in water suspension using several methods: photon correlation, absorption, Raman and IR spectroscopies. Sodium Deoxyribonucleat was chosen as a biological material. On the base of obtained results, the adsorption mechanisms are determined.
