FIELD: chemistry.
SUBSTANCE: invention relates to chemical methods of functionalising nano-sized objects for endowing their surface with certain properties. Nanopowder of metals or metal oxides in a carbon shell or without a carbon shell, or nanocarbon, or nanodiamond, react with a water-soluble arenediazonium tosylate salt for formation of covalent bonds of organic functional groups with the surface of the powder.
EFFECT: simplification of synthesis conditions with possibility of obtaining double-layer and single-layer particles having a surface with selective capacity to react with organic, bioorganic and inorganic substances or metal ions or their stabilisation in corresponding media during use.
